Synth modules

Notes: Super-versatile quad envelope generator and LFO source from the Vancouver Eurorack brand. All CV controllable and with tons of shaping options.

Supplier's notes:
The Intellijel Quadrax consists of four independent, CV-controllable channels, each of which can be configured to perform any one of the following functions:

- An AD (Attack, Decay) envelope
- An AHR (Attack, Hold, Release) envelope
- A cycling envelope (resulting in a unipolar LFO)
- A pulse burst generator (Finite repeated functions that ascend or descend in amplitude)
- A morphing, bipolar beat syncable LFO

The envelopes all feature a continuously variable response curve, ranging from logarithmic through linear to exponential, and each stage can be as snappy as 0.3 ms to as lengthy as 20 seconds.

When set to Burst mode, the channel generates a rising or falling burst of pulses, with full control over the length of the pulse burst, the number and shape of the bursts within it, and whether the bursts increase or decrease in amplitude over the burst.

AD, AHR, Cycling and Burst modes all feature a user-selectable maximum output level of either 5V or 10V.

LFO mode offers control over the frequency and waveshape, while providing a unique morphing feature that creates numerous variations of the selected waveshape. LFOs can be either free-running or beat-synchronized using the channel's TRIG input.

Channels can be chained together to create complex multi-stage envelopes, with each channel triggered by the previous channel's trigger input, end-of-rise, or end-of-fall. This enables multiple function generators to fire simultaneously, or it enables the creation of complex multi-stage envelopes by allowing the linked function to fire either at the end of the previous function's rise time, or at the end of its fall time.

Four freely-assignable, step-attenuverted CV inputs are capable of modulating any or all of the various parameters across all four channels using the built-in CV matrix, and built-in attenuversion for each assignment.

Quadrax remembers its current state (Mode and CV assignments, channel links, etc) and retains that state even if power is removed, meaning Quadrax will always turn on in exactly the same state as you last left it.

Notes: Module A-140-2 contains two ADSR type envelope generators behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V. The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR. Changing the positions of the mentioned jumpers allows to modify the factory settings.

Notes: The ‘Pip Slope’ (rev II) is a compact envelope and function generator. It supports both Attack/Decay and Attack/Sustain/Decay type envelopes with both direct and voltage control of Attack and Decay times. Envelope shapes can be morphed between exponential, linear and logarithmic type slopes. Envelopes can be made to loop, repeating infinitely or decreasing with time or amplitude for echo and bouncing ball type effects. An ‘End of Cycle’ trigger output further extends the envelopes functionality for both clocking and burst or fill type effects.

The improved Pip Slope adds a number of new features and updates over the original Pip whilst keeping the same size. Improvements include increased output resolution, finer control of fast envelopes, a new morphing shape control, switchable 5v or 8v maximum envelope level, additional loop modes and an additional trigger output.

Features:
Compact envelope and function generator in 4HP.
Trigger and gate inputs.
Voltage and direct control of attack and release times.
Snappy or super long envelope times – ranging approx 1ms to 7 minutes per stage.
Optional self looping ability with 3 different loop modes: Decreasing amplitude, decreasing time, and regular loop.
Shape control that morphs the envelope shape from logarithmic to linear to exponential curves.
End of Slope trigger output that fires a trigger at the end the envelope or loop cycle.
Selectable 5v or 8v max envelope level output.
Reverse polarity protection.
Skiff friendly.
Designed and Made in the UK.

Notes: Successor to the excellent Metropolis, the Metropolix is a performance-focussed step sequencer with some really neat features, including modulation and sub-sequences in Loopy mode.

Supplier's Notes:
The Intellijel Metropolix is a unique and powerful Eurorack format musical sequencer. With an abundance of hands-on, tactile controls and a wealth of modulation possibilities (both internal and external) you can quickly and easily create infectiously musical sequences that are never boring. Even the simplest riff can be brought to life with seemingly endless options to create variations or real-time manipulations. Equally at home in the studio or a live improvised performance, the Metropolix is sure to become a staple source of fresh ideas and killer riffs in your creative process.

Width: 34HP
Depth: 25mm
Power: 95mA @ +12V 10mA @ -12V

On first blush, it appears to be a simple 8-stage sequencer - but there is far more functionality than first meets the eye:

There are two tracks (TRK 1 and TRK 2) that are variants of the single master pitch/gate sequencer, which is programmed via the PITCH sliders, PULSE COUNT and GATE TYPE switches. Each track interprets the master sequence in a variety of ways - creating complementary sequence variations that enable you to generate counterpoint, polyrhythms, and all manner of sonic movement (both subtle and extreme). Each of these tracks has its own playback ORDER, sequence LENgth, clock DIVision, SWING amount, SLIDE time, and track GATE lengths. Other track-based sequence variables are accessible from the TRACK MENU, and include Pitch Slider inversion; sequence note range; track transposition; and more. In addition, Tracks 1 & 2 both have multiple lanes of per-stage playback parameters, including: GATE override; PITCH override; RATCHet count; PROBability of playback; ACCUMulating transposition, and a dedicated CV lane. Each stage also has a SKIP feature, and a pitch SLIDE option.

8 separate and individual MODulation lanes are accessed via the MOD button. Each MOD lane has 8-stages of modulation values and its own playback ORDER, LENgth, and clock DIVision; and each lane is routable to one of Metropolix' two assignable outputs or to dozens of internal destinations, allowing for some sophisticated and powerful self-modulation.

A trio of AUX inputs allows for external modulation of user-assignable sequencer parameters for even greater variation, while two assignable CTRL knobs give you direct access to the parameters you want to adjust most frequently during a performance. With dedicated Pitch/Gate outputs for both Track 1 and Track 2; two totally user-assignable outputs (A and B); and internal MOD routing, Metropolix features a wealth of patching opportunities.

Metropolix also features a Loopy mode, allowing you to instantly play back short sub-sequences, or even "play" the stage buttons directly (like a 'keyboard').

Metropolix stores up to 64 preset configurations (in 8 banks of 8 presets), and all live settings are stored in EPROM, ensuring that your Metropolix will always power up exactly as you left it - even if you haven't saved them to a preset. By default presets can change all the structural (menu-based) elements of your sequencer without overwriting the front panel controls, but full recall is also available.

The operation of the Metropolix is optimized for live performance and jamming, with quick access to all the most important performance parameters, and the ability to greatly affect your sequences with a single slider or switch.

Notes: The Mutant Brain is the central nervous system connecting your modular analogue eurorack system to MIDI gear, especially for percussion, polyphonic notes and sync duties! It packs 16 eurorack compatible outputs into a tiny, super affordable 8HP package.

The 4 CV outputs and 12 Gate/Trig outputs are all universally reconfigurable. Triggers, gates, clock divisions and sync signals, polyphonic keyboard playing, velocity, sequencer transport, LFOs - you name it!

Configuring your patch is easy - just assign each output as you like in the Mutant Brain Surgery configuration utility, then send the MIDI SysEx file to the module and forget about it - the Mutant Brain remembers it all for you.

Hexinverter supply a convenient download pack of pre-configured, ready to use Mutant Brain patches for some select sequencing and drum machine devices on the market today, easily turning those sequencers and drum machines into a modular control powerhouse!

Designed with live and studio performance in mind, the Mutant Brain does away with wasted panel space and complex menu-diving interfaces, while freeing you from the limited "auto-learn" type MIDI interface.

Notes: Small and efficient MIDI to CV courtesy of Intellijel's 1U series. Works in conjunction with an Intellijel case or the MIDI IN Jacks 1U module to give you Pitch, Velocity, Mod, CC, Gate, Trig, Clock and Reset.

Supplier's Notes:
The MIDI 1U system provides all the essentials to control and sync your Eurorack modular from your computer, mobile, or hardware MIDI device with a minimum of fuss. Several of the module's most important features can be changed using the two front panel buttons, with full configuration capabilities offered via the Intellijel Config app, which is available for both Mac and Windows. The connectivity, feature set, expandability, and compact size make the MIDI 1U system ideal for integrating your modular gear with the rest of your rig.

Intellijel's MIDI 1U system comprises several elements, which work together to provide flexible, programmable MIDI-to-CV conversion to your Eurorack modules: The system comprises two mandatory components, and one optional component:

MIDI 1U module - This 14HP 1U module receives MIDI from an attached, external MIDI input connector (7U case, Palette case, or MIDI IN Jacks 1U module), and extracts (by default) Pitch, Velocity, Mod, CC, Gate, Trig, Clock and Reset messages i sending the proportional voltages to individual 3.5mm jacks for patching.If desired, the CC and MOD jacks may be configured to respond to either Channel Aftertouch or High Resolution CC, and the Reset jacks can be configured as a Run jack, instead. Additionally, MIDI 1U features an alternate Dual Mode, which maintains the Clock & Reset functionality, but uses the other six jacks to transmit Pitch, Velocity and Gate messages derived from two separate MIDI channels.
MIDI input connector - the MIDI 1U module does not have its own MIDI input jack. This enables you to use the MIDI/USB inputs built-in to your Intellijel 7U Performance Case or Palette Case. If you don't own one of these cases, you can purchase the MIDI IN Jacks 1U module to connect an external MIDI device.
MIDI Expander 1U module - This optional 14HP 1U module connects to the MIDI 1U module and adds an additional eight 3.5mm CV outputs. These outputs are fully programmable using the Intellijel Config app, and greatly expand MIDI 1U's ability to control your entire Eurorack system.

Notes: Tune is a multi-scale pitch quantizer. It features 11 scales ranging from chromatic to octatonic with everything in between. In addition, the bias control allows the user to transpose the melody to a different octave or starting note.

This functionality opens up every musical mode for each of its 11 scales and provides a performable control for transforming melodies on the fly.

Notes: Multi-function eight-channel LFO, joystick, movement recorder and drone oscillator that packs in lots more functionality than you might expect. A real modulation powerhouse in a compact format.

Supplier's Notes:
Erica Synths Black Joystick2 is 8 channel multi functional CV and sound source - joystick, movement recorder, distinct LFO and drone/noise oscillator. It provides great interaction with the modular system and allows to develop unconventional modulation patterns instantly.

Notes: VCO:

- Tune: manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
- Oct: range switch -1 / 0 / +1 octave
- Mod: modulation depth (attenuator wired to the Mod. socket)
- Dest: switch that is used to address the modulation to frequency modulation (position FM) or pulsewidth modulation (positon PM), in centre positon no modulation
- PW: manual pulsewidth control for rectangle waveform, PW can be also modulated by the Mod. input as mentioned above
- Wave: waveform switch (sawtooth / off / triangle), the sum of the waveform chosen by this switch and the rectangle is fed into the VCF (to turn the rectangle off the PW control has to be set fully CCW or fully CW)
- 1V/Oct. (socket): external CV input for VCO frequency (1V/octave)
- Access to internal bus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)
- Triangle core VCO, frequency range about 32Hz ... 8kHz

Balance unit:

- The balance unit is made of two VCAs which are controlled by the sum of manual Balance control and the balance CV input in the opposite direction.
- The audio input of VCA1 is hard-wired to the VCO output, audio input 2 is connected to the socket Ext.In.
- The output of the balance unit is used as audio input for the VCF
- Bal.: manual balance control, fully CCW the internal VCO is used, fully CW the external signal (Ext.In) is used, at centre position both signals have about the same level
- CV Bal.: CV input for balance (range about 0...+5V)
- Ext. In: external audio input for VCA2, about 5 Vpp level required for similar loudness as the internal VCO
- This socket is normalled to the internal VCO suboctave f/2 signal (rectangle with half the frequency), if no external signal is applied the suboctave signal is used as the second signal for the balance unit

VCF:

- 24 dB low pass
- Frq: manual frequency control
- FM1: frequency modulation depth (attenuator wired to the VCF FM1 socket, the socket is normalled to the internal Envelope signal and then FM1 controls the modulation depth of the internal envelope applied to the filter)
- FM2 (socket) : second CV input for VCF without attenuator (about 1V/octave), can be used e.g. for VCF tracking by connecting the same CV which is used also for the VCO frequency
- Res: manual resonance control (up to self oscillation)
- If the VCO is turned off (waveform switch = centre position, pulsewidth control = fully CCW or CW) and the VCF resonance is set to maximum the module can be used as a sine oscillator, the tracking at socket VCF FM2 is about 1V/octave (not as precise as the VCO but much better than most other filters)
- ~ 11 octaves frequency range (~ 10 Hz ... 20kHz)

VCA:

- Gain: manual amplitude control (initial gain), can be used to open the VCA without envelope signal
- VCA (switch): used to switch between gate and envelope as control signal for the VCA, in centre position the VCA is not controlled by envelope or gate
- Note: when gate is used the VCA is controlled directly by the gate signal (i.e. hard on/off), this may lead to clicking noise under certain conditions (especially with low VCO/VCF frequencies)
- Special control scale: exponential scale in the range from about -20dB to -80/90dB, linear scale from about -20dB to 0dB
- Remark: this special control scale results in a loudness behaviour that is a bit different from pure linear or exponential VCAs
- Out: audio output of the module (= VCA output)

Envelope:

- Gate (socket): Gate input (min. +5V), can be normalled to the bus gate signal by means of a jumper
- Att: manual control for Attack
- D/R: manual control for Decay/Release
- Env. (switch): used to switch between A/D, ADSR and A/R mode of the envelope generator, in centre position (ADSR) the sustain level is fixed to about 50%
- Envelope (socket): envelope output (about +10V)
- CVT (socket): CV input for time control, by means of two internal jumpers one can select which time parameters are controlled by the CVT input (e.g. A only or D/R only or A/D/R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question)
- Envelope LED display
- Attack time range: ~ 1ms ... 5 sec (can be extended by using the CVT input)
- Decay/Release time range: ~ 1ms ... 15 sec (can be extended by using the CVT input)

Notes: ***Now featuring Assimil8or Software Version 2.0! Available to download here: http://www.rossum-electro.com/products/assimil8or/

The ASSIMIL8OR is a CV/Gate-controllable sampler with eight independent channels. Each channel is not only its own voice, but also has a separate audio output and a gate/trigger and three CV inputs. Given ever get two sample inputs and main outputs. Thus, Stereo Sampling and playback is possible. Mixed operation of stereo or mono is possible and is limited only by the maximum number of eight channels or parts.

The ASSIMIL8OR works with high-quality 24-bit AD and DA converters. Internally, however, sample and bit rate for lo-fi sound can be lowered, the latter is even CV-controllable. The samples can also be otherwise manipulated in many ways. Thus, the phase of a sample via CV or a different sample can be modulated. Likewise, the loop points can be controlled and the sample can be traversed with CV control (scrubbing), whereby wavetable similar effects could be achieved. The following parameters can be addressed via the gate / trigger and CV inputs:

- Pitch
- Level
- Bit Depth
- Phase Modulation
- Pan
- Scrub
- Sample Start
- Sample Length
- Loop Start
- Loop Length
- Release Decay

Samples and presets are stored on an SD card, which is easily accessible plugged into the module front.

Notes: The module contains two ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor) behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V (10V = attack peak).

The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR.

Notes: Javelin is a module that is basically an ADSR envelope with integrated VCA. However, it has several features that make the module an expressive sound shaping tool.

Three level ranges determine the total amplitude of the envelope, additionally three different time ranges are integrated, which can be switched between.

The accent behaviour is also unique. If several gates are applied to the Accent input at the same time, the envelope rises slightly with each gate.

Features:

Attack-decay-sustain-release envelope
Integrated VCA
Unique accent behaviour for expressive sequences
Reset input
CV control over attack and release
Looping mode for LFO-like modulations
Mode switch for gate and trigger behaviour
Linear, moderate or steep exponential shape
Short hold in the peak of the attack for more punch
Power consumption: 93mA at +12V and 65mA at -12V

Notes: Clep Diaz is a handy and small step CV and LFO generator. In step and random modes, use the encoder to control the number of steps in the sequence; in LFO mode, the encoder controls the amplitude of the wave. Toggle the directionality of the sequence: up, down, or up/down to customize the CVs further. CD also gives CV control over the number of steps in the sequence and an end-of-cycle trigger output. Unipolar and bipolar outputs allow maximal control.

Notes: AXON-2 is an 8HP expander module for the SQUID SALMPLE, MFX and Pamela's PRO Workout that like the AXON-1 provides 4 additional freely assignable CV inputs but additionally adds manual offset controls and 2 additional 'performance' buttons.

The addition of AXON-2 increases the Squid, MFX or Pam PRO's total number of CV inputs by 4, greatly increasing the possibilities for vast modular manipulation. Each of the CV inputs includes an offset for hands on control over parameters assigned to CV. Per assignment digital attenuation and offset via the host module is also available for fine tuning the modulation or control over parameters.

The AXON-2's large buttons are great for controlling select functions in a live performance environment or adding convenient quick navigation shortcuts when making edits. The buttons functionality and assignability are dependent on the host module. See respective manuals for details.

NOTE: AXON-2 support requires the latest firmware be installed for Pam Pro (120 or newer), Squid (187 or newer) and MFX (105 or newer).

Features
4 Additional freely assignable CV inputs for the SQUID SALMPLE, MFX or Pamela's PRO Workout

Notes: Simple but effective four-channel module, allowing you to attenuate or offset CV or audio signals. Normalled 5V source on each channel allows you to generate a standalone CV signal without an input.

Supplier notes:

4TTEN (pronounced either ATTEN or FOUR-TEN) is a four channel attenuator and offset generator.
Use 4TTEN to attenuate any CV or audio signal by running through the ins and outs.
A +5V voltage source is normalled to each input, making it a standalone offset when there is no cable patched into an input.
Each channel is completely independent.
Ever-so-useful in live performance, we designed this module with 4 sliders for easy maneuverability, visual feedback, and enjoyable to play interface. Make your eurorack modular synthesizer system more playable with 4TTEN!

Notes: Two independent Contour Envelope Generators in a single 12hp wide Eurorack module. These are very accurate replicas of the Model D contour generators, with identical circuitry and component values running on the correct +9.3V and -10v supply voltages of the original; so they exactly replicate the original envelope response along with all of it eccentricities. Extra features include manual trigger buttons and envelope status LED's.

The contour generators played a larger part in the sound of the Model D than many people realise. There are two factors that make them unique, firstly the exponential slope when is used in conjunction with the (near) linear slope of the original VCA which is responsible for the famous Model D "punch". Secondly, the re-trigger behaviour is quite unique, multiple retriggering increases the output level so that either the volume increases incrementally, or the filter opens incrementally with each extra key press.

AJH Synth have added independent Decay switches for each individual Contour Generator rather than the shared switch on the original synthesiser, these switches change the Contour response from AD (switch up) to ADSD mode (switch down).

Notes: Expander module adds four more assignable CV inputs to Squid Salmple for advanced modulation and sample manipulation. A must for all Squid Salmple owners.

Supplier's Notes:
AXON-1 is a 4HP expander module for the SQUID SALMPLE that provides 4 additional freely assignable CV inputs.

The addition of AXON-1 brings Squid's total number of CV inputs to 7, greatly increasing the possibilities for vast modular sample manipulation.

Each modulation assignment includes digital attenuation and offset and behaves just like Squid's 3 built in CV inputs.

AXON-1 requires firmware 166 or later installed on the Squid Salmple to function!

Notes: A true legend of modular synthesis, Make Noise's Maths is arguably the definitive Eurorack function generator. Based on analogue computing circuits, Maths draws on Buchla-style techniques to offer countless ways of generating and processing modulation signals.

Notes: Delta-V is a fully analogue dual-channel function generator, featuring a dedicated VCA and LFO cycle switch for each channel. It packs a great deal of functionality in only 10HP, and will surely find use in almost every patch.

Generate envelopes, slew gates and signals, or run LFOs with precise control over attack and decay times. Using the SHAPE knob, Delta-v can create a wide range of envelopes, from very snappy exponential curves for percussion to logarithmic thumps for bass lines.

If VCA's input is unpatched, the module outputs a regular voltage envelope. When an audio signal is patched into the VCA input, the output signal becomes the audio signal amplified by the envelope.

Sending other envelopes or an LFO to VCA input lets you modulate those modulators, quickly creating complex control voltages that go beyond the usual attack-decay envelope.

Combine this with the SUM output, which sums the two channels, and the attenuverters, which can quickly attenuate or invert the signal, and you have a whole array of signal processing capabilities.

The TRIGGER input fires a Attack-Decay envelope, while the SLEW input will affect the rate of change of the signal.

The trigger for channel 1 and 2 can be linked together, so you can fire two envelopes with one patch cable.

Each channel has an End of Cycle output, (EOC) this outputs a short trigger at the end of each envelope cycle.

The output voltage ranges from -10 to +10 volts, set with handy output attenuverters.

The CYCLE switch starts looping the envelope, creating LFO's that go up to audio rate, and that can also be used as an interesting sound source.

There are many ways to utilise Delta-V.

Notes: ADSR is a four stage linear envelope with two expressive ranges. Each stage can be modified independently allowing for the creation of complex, multi-segment envelopes. Great for modulating filters, VCAs, and oscillators.

Notes: The hands-on control of hardware meets the versatility of software. Bridging the gap between Eurorack and VCV Rack, the MetaModule includes over 160 built-in modules plus access to over 200 third-party options.

Supplier's Notes:
The MetaModule puts real knobs and jacks on virtual software modules. Step back from the computer and make music with hardware, while keeping the flexibility and expandability of software.

The MetaModule comes with over 160 built-in modules from 4ms Company, Befaco, HetrickCV, NonlinearCircuits, and Scanner Darkly, plus clones of popular classics such as the Mutable Instruments eurorack modules, fun physical modeling algorithms, and lots of handy utilities.

All of the included modules are also available on the computer using the free program VCV Rack. Whether you make patches on VCV Rack and transfer them to the MetaModule, or if you just create patches directly on the MetaModule, there are plenty of creative modules to inspire new ways to make music.

MetaModule Plugins

If the 160+ built-in module aren't enough, you can load more modules as plugins. Already there are over 200 modules in third-party plugins from Bogaudio, Valley, ChowDSP, NANO Modular, and the list is growing. 4ms have an SDK available to make it easy for VCV Rack plugin developers to convert their plugin to a MetaModule plugin. 4ms' licensing terms are non-restrictive: developers are welcome to distribute their plugin in any way they wish, commercially or not.

Mapping Knobs and Jacks

The MetaModule has 12 knobs that can be mapped to virtual knobs. Each knob can be mapped to up eight virtual knobs, and each mapping can have a different range and offset. You also can save a group of mappings as a Knob Set and switch between Knob Sets with the encoder. You also can map the 8 inputs and 8 outputs to virtual module jacks. Also, the MetaModule is a USB MIDI host, so you also can map MIDI CC, note, gate, and other parameters to knobs and jacks.

Expanders

There are lots of ways to customize your MetaModule. A Wifi expander allows you to wirelessly transfer patches from your computer. Add eight more knobs with the Knob expander, or buttons with the Button expander. A CV/Audio expander adds more high-resolution inputs and outputs, and the Gate In/Out expander adds not only gate jacks but also TRS MIDI and I2C.

Under the Hood

There are six CV/Audio inputs, two gate inputs, and six CV/Audio outputs. The CV/Audio jacks are all 24-bit, 48kHz DC-coupled, -10V to +10V. A USB-C jack accepts MIDI devices and thumb drives. Patches and plugins can be loaded via a USB drive or microSD Card, and internal flash memory lets you save patches you always want to come back to.

The processor is more advanced than anything 4ms has used in the past, and is among the most powerful processors found in Eurorack. Startup time and latency are blazingly fast.

Notes: Dual xFade is a compact voltage controlled crossfader suitable for both audio and CVs. Smaller knobs set manual crossfade between A<>B, and bigger knobs are CV attenuverters. LEDs show the adjusted positive and negative CV sides for easy monitoring.

Upper inputs (section 1) are normalled to lower inputs (section 2). Thus the same signal pair A&B can be differently crossfaded in both sections.

The switch clones section's 1 controls to the section 2, which is useful to make stereo Dry/Wet adjustment or stereo VCA.

This module can be used as:

two independent crossfades

two independent VCAs

stereo crossfade or Dry/Wet control

stereo VCA

panner

Four jumpers on the back can give optional 5x amplification for each A or B input. Sot it is easy to crossfade modular level with linear level from pedals. Installed jumpers give 1x amplification, removing jumpers gives 5x amplification.

Output 1 is mixed with output 2 if left unconnected.

Notes: Erica Black Series include high-end, unique functionality and superior quality modules. Only the best, highest quality components are used, all inputs and outputs are protected against undesired overvoltage. When designing Black Series, put Erica Synths prioritised design and usability first Big knobs are assigned to functions that make difference in sound. Erica Black series consist of range of modules that are needed to put together entire synth. Enjoy!

The Erica Synths Black Dual ASR EG is a versatile, full analogue voltage controlled looping envelope generator and low frequency oscillator with manually and voltage controlled shape and rate, designed for use in advanced modular systems.

It has two identical parts, each featuring all typical envelope generator controls and bonus features - the end of the cycle output and bi-polar LFO output. When in loop mode the shortest attack and decay settings turn the module into voltage controlled drone oscillator with adjustable waveform (it will not track 1V/oct, though).

Notes: Pons Asinorum is a compact four-channel multimode envelope generator and LFO with voltage control. PA has three different envelope shapes, CV over cycle length, and a unique single encoder control scheme that makes adjusting multiple channels mid-performance easy. Channels can be set separately to envelope mode or to cycle in LFO mode, giving PA maximal flexibility in a minimal footprint.

Notes: Kermit is a 4-channel programmable supermodulator with morphing wavetable generator and internal modulation matrix. Four channels operate as LFOs, audio rate oscillators (with 1v/octave response on two channels), 1-shot envelopes, random voltage generators, or sample-and-holds, all responding to manual control, external control voltages, or synchronization to the module's master tap tempo clock. Designed for maximum patching power in small systems, Kermit carries an unmatched functionality-per-HP factor with an easily readable display that shows parameters in their real-world units.

The module has a 16-bit DAC to accurately render subtle changes of voltage at extremely low frequencies. The oscillator mode is best suited for bass frequencies, and the waveform "character" modes restrict the morph behavior or degenerate the audio to a minimum of 8 bits with limited horizontal resolution, like the Konami SCC chip used with the MSX computer. The tap tempo facility features an input jack and a manual button. The tempo is shown on the OLED display in BPM. The relevant units (hertz, seconds, volts, etc) or selected waveform of each channel are contextually shown on the display as the user programs the module.

List of operating modes per channel:

LFO (1 volt/octave)
LFO (with reset)
Tap tempo LFO
Audio oscillator
Audio oscillator (unison)
Code scan
1-shot envelope
Gated repeat envelope
Tap tempo envelope
Smooth random
Stepped random
Tap tempo stepped random
Sample-and-hold
Track-and-hold
Tap Tempo sample-and-hold

Three parameters on each channel can be modulated: frequency, amplitude, or waveform. Both external CV input and internal cross modulation are programmable with hotkeys. For example: assign the output of Channel B to morph the waveform of Channel A by holding the Channel B button while turning the Channel A Waveform knob. All channels have manual control of frequency (coarse and fine), phase, wave bank, waveform morph, and amplitude. Channels A and B have full controls, C and D have single knob controls with deep parameters accessible by hotkey combinations. Still deeper functions are accessible through the Mark III menu system.

Kermit has a microSD card slot for loading custom waveforms, like its big brother Piston Honda. The SD card accepts one .WAV file in WaveEdit format (free software editor) containing 64 waveforms, also compatible with several other Eurorack modules. When loaded into Kermit, the waveforms are organized into 8 banks of 8 waveforms each. Each oscillator can select any of the 8 banks, and the 8 constituent waves can be smoothly morphed from one to another.

The Mark III morphing preset manager is in full effect on Kermit. The discrete preset mode quickly and reliably recalls all parameters in response to triggers or CV, accessing the true power of the module as detailed, carefully programmed settings are effortlessly loaded and changed. The morphing mode causes delightfully unexpected variations of the basis preset.

Insert a master clock signal and you're ready to go. Kermit is a reliable provider of endless rhythmically coherent modulation voltages and a reasonably competent "voice module" providing most common synthesis functions on each channel with an internal modulation matrix.

Notes: A compact attenuverting (attenuator-inverter) joystick controller and Gate Generator. With it, you can generate and process two control voltages using only one hand. Provided controls for CV ranges and offset adjust the boundaries of your control, this way it never gets out of the desired range, ensuring sensibility and playability even with wild performance gestures.

Designed, kits prepared and completed modules assembled in Barcelona.

Notes: The Control Voltage Processor from Verbos Electronics GmbH is a suite of control voltage processing possibilities divided into 3 sections in a slim 18HP package. The lower 2 sections are DC coupled mixers that allow mixing, inverting, offsetting, scaling, multiplying, dividing, crossfading or a combination of these functions. The top section is a voltage controlled slewing processor with independent control of Positive and Negative slew rate, with some unique tricks. The Positive and Negative slew, or Rise and Fall rates if you like, have reversing attenuators. The slopes can be blended from linear to RC curves (starting all slides fast and ending slow, like a proper "East Coast" Portamento) without a change in speed. It can be triggered like an AD envelope and has a Gate out that goes high when the CV out is below 100mV. Of course it can loop by patching the Gate out to the Trigger in. The Bounce control adds a unique flare of overshoot to CV changes, a bit like the effect of stopping a tape reel from turning and then letting it go. The combination of multiple voltage processors offers the user the functions of analogue computer.

Notes: A clever hybrid of quad VCA, function generator and more in this chunky module. Four channels of oscillators, envelope generators and VCAs, plus slew, voltage sources and plenty of CV control.

Supplier's Notes:
Four channels of function generator, oscillator, slew limiter, envelope, and VCAs. This module brings the ultimate in flexibility as it can be used as a standalone synth voice, a massive amount of modulation, or a four channel envelope generator w/ mixer. We believe this makes QARV a great first module and a great addition to the largest of systems.

All four channels have the following features:

Uni-polar oscillator mode
Attack and release time control via potentiometer and via input jack
Shape control that controls shape for both attack and release
Output attenuverter
VCAs that normal to each subsequent channel (CH1 -> CH2, etc.). So you can get a mix of all four channels out of the CH4 VCA output (unless you patch a VCA output from an earlier channel)
Channels 1 & 4

Voltage source (CH1 - 5V & CH4 - 10V)
CH1 & CH4 can be switched between IN (slew mode) and TRIG (envelope) mode
RISE and FALL gates. You can use our G&T module to turn these gates into triggers.
Channels 2 & 3:

Bi-polar oscillator mode
Dedicated IN and TRIG jacks (helpful for adding offset to a triggered ENV)
BOTH input jack to simplify patching both the attack and release (also inverts the input to give more standard pitch tracking of higher voltage equals higher pitch)

Notes: Tangrams

Push (or Pulse) the Envelope

Snappy, classically analogue envelopes with visually intuitive controls. Add a powerful, cv controllable cyclical gate generator, integrated VCA, and trigger buttons -then double it-now you've got Tangrams.

Tangrams, like the Dual ADSR before it, is a dual analogue core-envelope inspired by the Roland SH-101 / System 100m design with several enhancements. Taking further inspiration from trapezoidal function generators like the one on the EMS Synthi, Intellijel have added a voltage-controlled pulser circuit to link the triggering of two envelopes - allowing for delayed one-shots, cycling organic envelopes, and more. In addition, Intellijel added two VCAs for level control of each envelope, or alternatively, direct injection of the signal you'd like to envelope - freeing up your other VCAs.

The Pulser

The Pulser can be thought of as a way to set both a gate ON time (T1) and an OFF time (T2). In this way, you could configure a cycling ADSR that has a gate time that is different from the interval between gates. Alternatively, you can create a sequence where ADSR2 is triggered by a delayed amount of time after ADSR1 is triggered (either cyclically or in a single shot sequence). The panel switches for routing or disabling the pulse sources allow for even more complex combinations of control beyond these examples. This special combination of functions can yield a plethora of interesting and organic envelope and gate patterns to be created; cyclical and single shot.

Notes: The Z4000 NS is a snappy voltage-controlled analog envelope generator with a built-in CV processor for scaling, inverting, and voltage-controlled deviating of the envelope shape. The Z4000 generates an envelope made of the four classic segments: Attack, Decay, Sustain and Release, in which each segment can be manually set using knobs or dynamically set under voltage control.

Control knobs for the Attack, Decay, and Release segments are scaled. The first 0-50% of the knobs rotation is dedicated to high resolution adjustment in the millisecond range.

The output levels are fully adjustable with signals that can reach up to 10V in either polarity and can be mirrored into the opposite polarity or clipped using the voltage-controlled deviater-scaler. A bi-color LED indicates intermediate values in both polarities and their crossfade state.

The Attack slope switch allows selection of a logarithmic or exponential curve for the Attack segment. This subtle effect helps further the fine adjustment of the Attack segment slope. A Shoot button is provided to let you fire the envelope manually. The Z4000 also provides a retrigger input allowing you to create legato notes when using a classic keyboard interface.

Going down to nuts and bolts, the Z4000's smoothness and snappiness is made possible by a four segment active-charge discrete circuit which is an extended version of circuits found in classic two segment rise / fall transient generators.

Notes: *** Free software update available as a free download, along with updated documentation, at the Mob of Emus product page on the Rossum Electro-Music website***

A lot to unpack here. Six-channel multipurpose oscillator/noise source/modulation generator with quantisation, trigger generators and even more. Seriously powerful all-round digital goodness.

Supplier's Notes:
Mob of Emus is a powerful music and sound design tool that packs an enormous amount of creative power into an amazingly compact 16HP module.

Mob of Emus gives you six channels of oscillators, noise sources, cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes), sample and hold waveshapes, slow random modulators, triggers, rhythm patterns, and quantization (of both internal and external signals) in pretty much any combination (well, any combination of six channels, anyway).

In addition to being able to independently program the function of each individual channel, Mob of Emus' Hex Mode provides a macro control layer that allows you to control all of its channels simultaneously (while maintaining the relationships of each channel's independent programming).

What's more, Mob of Emus' "harmonic" control structure makes it extremely easy to combine its oscillators into rich additive timbres, to combine its LFOs into stacked harmonic low frequency modulation waves, and to create modulation sources and triggers with intricate polyrhythmic patterns.

With an external trigger input, six CV inputs that can operate in six different control modes, six independent outputs, and an assignable mix output, Mob of Emus can operate as the heart of an almost unlimited variety of patches. And its 8 real-time controls will give you immediate hands-on access to a channel's (or all six channels') key parameters, inviting (and rewarding) exploration and improvisation.

Mob of Emus features include:

Six channels that can function independently or can be further controlled by a Hex Mode macro layer that lets you control all six simultaneously. Channels can be:
Wide-range digital oscillators
Noise sources
Cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes)
Sample and hold waveshapes
Slow random modulators
Triggers
Rhythm patterns
Quantizers (of both internal and external(!) signals)
Six CV inputs that can function in six different control modes
Eight real-time controls for immediate access to key channel parameters
Six individual channel outputs and an assignable mix output
The ability to store and recall 12 user presets
And much more.

Mob of Emus is 16HP wide and 25mm deep.

Power requirements (max): 130mA +12V, 25mA -12V. Reverse polarity protected.

As of March 2021, there has been a been a small bug fix to the recent software update for Mob of Emus.

The update fixes a bug where holding the Channel Selector Buttons for a short time to select a single channel and deselect any others was not working correctly.

The update fixes a bug where some Hex Mode parameters were not ignored when Hex Mode was set to off.

The update introduces a feature allowing users to double-click and hold the Hex button to reset all Hex Mode parameters and set Hex Mode to on.

Rossum Electro-Music made a change to the behavior of the LEDS when using the utility 'Display Software Revision'

Notes: The CVx 1U expander module has eight user-configurable outputs and connects to the MIDI 1U module. Using the Intellijel Config app, you can assign each of the eight jacks to generate just about any type of voltage that can be derived from a MIDI signal; pitch, gates, triggers, clocks, velocity ... you name it! You can chain up to four CVx modules to a single MIDI 1U to add a whopping 32 additional channels of midi control to your modular.

Each CVx module can also allow you to generate 2 or 4 voice polyphonic controls with selectable voice allocation modes. The connectivity, feature set, expandability, and compact size make the MIDI 1U + CVx system ideal for integrating your modular gear with the rest of your rig.

Intellijel's MIDI 1U system comprises several elements, which work together to provide flexible, programmable MIDI-to-CV conversion to your Eurorack modules: The system comprises two mandatory components, and one optional component:

MIDI 1U module - This 14HP 1U module receives MIDI from an attached, external MIDI input connector (7U case, Palette case, or MIDI IN Jacks 1U module), and extracts (by default) Pitch, Velocity, Mod, CC, Gate, Trig, Clock and Reset messages - sending the proportional voltages to individual 3.5mm jacks for patching.If desired, the CC and MOD jacks may be configured to respond to either Channel Aftertouch or High Resolution CC, and the Reset jacks can be configured as a Run jack, instead. Additionally, MIDI 1U features an alternate Dual Mode, which maintains the Clock & Reset functionality, but uses the other six jacks to transmit Pitch, Velocity and Gate messages derived from two separate MIDI channels.

MIDI input connector - the MIDI 1U module does not have its own MIDI input jack. This enables you to use the MIDI/USB inputs built-in to your Intellijel 7U Performance Case or Palette Case. If you don't own one of these cases, you can purchase the MIDI IN Jacks 1U module to connect an external MIDI device.

CVx 1U module - This optional 14HP 1U module connects to the MIDI 1U module and adds an additional eight 3.5mm CV outputs. These outputs are fully programmable using the Intellijel Config app, and greatly expand MIDI 1U's ability to control your entire Eurorack system.

Notes: Module A-147-2 is the successor of the VCLFO A-147 but offers much more features than the predecessor. The module is made of these sub-units:

- VCLFO: voltage controlled low frequency oscillator
- VCA: voltage controlled amplifier, switchable to voltage controlled polarizer
- VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato/tremolo)

LFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset/Sync input. Triangle/Sine and Rectangle are displayed by means of dual-colour LEDs (probably red/green), Sawtooth has a unicolor LED available (probably blue). The output levels are about -4V...+4V for Triangle, Sine and Rectangle. The Sawtooth level is about 0...+8V.

The CV control can be switched to attenuator or polarizer ("CV Mode" switch). In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the centre position. In the centre position CV has no effect and right from the centre the control works like a normal attenuator. The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per period) to 200 Hz (with external CV max. frequency about 1kHz). In addition a ultra-low mode can be activated by means of an internal jumper. When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the "LFO CV" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible. For this a jumper has to be installed on the pin header JP6. In the factory a dummy jumper is installed on the pin header JP7 "Dummy". JP7 has no function and is used only for "parking" of the jumper. Simply remove the jumper from JP7 and plug it on JP6. JP6 is located behind the CV control.

VCA: This is a linear VCA that can be switched to "normal" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer ("VCA Mode" switch). In the "normal" VCA mode amplification +1 is achieved with about +5V control voltage. In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed. Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).

The VCA of the A-147-2 has three sockets available: "In" (signal input), "Out" (signal output) and "CV" (control voltage input).

The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the "VCA In" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the "VCA In" socket. The VCA can be used also independently from the LFO and the Delay CV. In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator/attenuator A-183-2).

Attack/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter "Delay" (or Attack) available. This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V. Then the voltage remains at +5V until the next Delay Reset occurs. The inclination or gradient is controlled by the manual Delay control and the Delay control voltage ("Delay CV" input). The waveform is linear, the control scale is exponential. The output voltage is displayed by a green LED and available at the "Delay Out" socket.

The manual Delay control ranges - without external "Delay CV" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the "Delay CV" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO)!

The Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the "Delay Reset" sockets resets the Delay output voltage to 0 V.

"Delay Out" is normalled to the VCA CV input by means of the switching contact of the "VCA CV" socket and consequently controls the Triangle level provided that no other patch is made. A typical example is the usage of a Gate signal (e.g. from a USB/Midi-to-CV/Gate interface) as Delay Reset. That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA.

Notes: Part of TipTop's exceptional series of Eurorack-format Buchla modules, the 264t provides four sample-and-hold circuits, plus a logic circuit designed to control polyphonic patches. Deceptively simple but surprisingly creative, like most Buchla modules.

Supplier's Notes:
Four independent sample-and-hold circuits, plus a specialized logic circuit for expediently implementing polyphonic patches.

Sample-and-hold's are essentially one-cell analog memories. They are useful for "remembering" the instantaneous value of a control voltage (a detected envelope, for example), for generating equally spaced steps from a constant slope input (as from a 281t envelope generator), and for converting any continuously changing voltage (a random voltage, for instance) into a series of discrete values.

The 264's sample-and-hold circuits have two operating modes: sample and track. In the sample mode, the value of the input is sampled and applied to the output whenever a pulse is received. The output remains at this value until the next pulse arrives. The track mode diers in that an input is applied to the output for the duration of the pulse. The output tracks the input until the end of the pulse and remains at a constant value until the next pulse.

To use the 264t as four independent channels set the separate/common switch to separate. A single CV can be set to all four channels by setting the operate/common to common and plug CV in the the back jack on the with right side.

The Model 264t includes a polyphonic adaptor, which performs the logic necessary to implement four-voice polyphony. Facilities are incorporated for fine tuning and f.m. modulating the oscillators; light emitters display the adaptor's operation.

Notes: CONTROL FORGE's core functionality is drawn from the E-mu Morpheus's insanely powerful (but hard to program on a two-line display) Function Generators. But now expanded into a supremely flexible modulation source encompassing elaborate one-shot contours, evolving cyclical patterns and sequences of arbitrary length and complexity.

- At its most basic, it's an 8-segment function generator with variable time and target voltage level for each segment.
- Each segment's level can be defined either absolutely or relative to the ending level of the previous stage and can optionally be quantized to the nearest 1/12 volt.
- Each segment's level may have a user defined range of randomness of either linear or gaussian distribution.
- A new 'Tempo Mode' lets you specify each segment's length in musical note values relative to a tempo set in BPM.
- The time scale may be modulated under CV control or manually via the encoder during runtime.
There are 67 different transition shapes between segments (indicated graphically on the display during selection), from linear and exponential shapes to various flavours of random, chaotic, and many more that don't lend themselves to one-word descriptions, including the ability to pass CVs directly through to the output for individual segments.
- Also included are 'DC' shapes that allow the module to be used as a sequencer with all of the module's available programmability. When combined with the Preset Sequencer described below, sequences can be hundreds of steps long and modified in real time manually or by CVs.
- Each segment may optionally have a conditional jump mode that results in a jump to another selected stage if a particular condition is met. E.g., a CV being above or below the selected conditional value, the presence or lack of a gate or logic high at their respective inputs, rising or falling edges at the inputs, etc. So, in addition to one-shot shapes, extremely elaborate cyclical patterns can be programmed that evolve based on the various conditional inputs.
- Control Forge's AutoChain functionality allows the creation of two very specific kinds of multi-preset patterns: A multi-preset retriggerable pattern (like a long syncable LFO), and a multi-preset 'envelope-like' pattern with retriggerability, an optional sustain section, and a 'release' section that's jumped to on gate fall.
- Two independent triggers can be programmed to fire in response to a variety of events and can be used to affect either CONTROL FORGE itself or external modules.
- 500 presets can be saved and recalled
- A preset sequencer allows stepping through up to 200 user-defined series of presets under trigger, clock or manual control. This allows contours and sequences of almost unlimited length and complexity.
- All presets and sequences can be transferred to any number of Satellite modules, which can then operate as stand-alone modulation sources, completely independent of the Control Forge.
- Like all Rossum Electro-Music digital modules, all parameters are available for adjustment with a single button press. No menu diving.

Notes: Explore modulation beyond the standard ADSR with Verbos's complex polyphonic envelope, opening up the potential of ADAsR and AHDsR slopes. Use the four envelopes independently or trigger sequentially in three separate modes.

Supplier's Notes:
The Verbos Polyphonic Envelope module is a set of four envelope generators which can be used together or independently. Cascade logic allows the four envelopes to trigger sequentially with subsequent envelopes starting at the Hold, Decay or End of the previous envelope.

Each envelope offers its own gate input, CV output and end pulse output, so it can be used in up to four-voice polyphonic patches. The three skew controls allow the times to change as each new envelope is switched on. All parameters can be voltage controlled.

Power consumption: 75mA at +12 V and 30mA at -12 V

Notes: A unique analogue percussion module, based on principles from the legendary 909 twisted into new sonic territory. Capable of everything from classic kicks and snares to more experimental hits and complex VCO effects.

Supplier's Notes:
A machine is born

The Machine began as a quest to create a rich-sounding eurorack snare drum synthesis module to complement the existing Mutant Drums. The project quickly became too large and costly to justify the module being capable only of snare drum sounds. So, the decision was made to learn from the architecture of the TR-909's snare and kick circuits, in order to develop a module capable of generating multiple forms of analogue percussion, and various other effects.

Like the other Mutant Drums, the Machine has its roots in classic analogue percussion synthesis. Even though it can create totally alien sounds, it still has the capability to deliver those classic 909 house snares and kicks if you want them. There are no microcontrollers in the Machine. The signals and waveforms are all generated by discrete components and ICs, for a distinctly analogue sound, and user experience.

Notes: Gross, gritty, and dark industrial-strength voice on a swappable oscillator platform. Pangolin approved.

Manis Iteritas Alia is a voice based on the architecture of Basimilus. It was designed to be grittier and more aggressive by using only sawtooth waves that are manipulated, modulated, and distorted through a rethought interface. Manis Iteritas Alia is fantastic for leads, basslines, drums, darkness, detuned swarminess, or pure mayhem. Plus, MIA's dedicated envelope output is a great modulation source for the rest of your patch.

MIA is available on Noise Engineering's 10HP Alia oscillator platform. Buy an Alia module and use the included USB cable to connect to the Noise Engineering Customer Portal to check out any other Alia firmware, free of charge, any time.

A portion of the proceeds of every Manis Iteritas Alia sold goes to pangolin conservation.

Notes: Mr. Phil Ter is a module that does a whole bunch of analog and digital stuff, in not a lot of HP.

Phil's digital bits are solely comprised of the envelope generator, for your envelopy pleasure.

The analogue bits, developed in partnership with the folks at Pittsburgh Modular Synthesizers, and are comprised of a voltage controlled amplifier circuit (VCA) as well as an extra juicy old-school transistor ladder filter, perfect for those of you who are not afraid of ladders or transistors.

Anyway, pair Mr. Phil Ter up with any oscillato,r or crank up its own filter section's resonance, and self-oscillate, get crazy.

Gate trigger threshold voltage: +5V

Attack, Release, and Decay times 0-10s (slow). 0-5s (fast)

Easter egg mode - quantize itself to 7bit for a steppy sample & hold effect

VCA facts - It's a VCA, not YMCA or YWCA, but made with love. Sound or voltage goes in, and it will come out, or not. Control it with voltage or not. You can never have too many VCA's, and this a good one.

Filter facts - Classic low-pass transistor ladder filter design, also will self-oscillate when resonance is cranked, creating a super clean trackable sine wave

Notes: Building on the familiar dual VCO core arrangement of Carrier and Modulator, Mindphaser is a complex oscillator which departs from this bit of ancestral DNA with a modern toolkit focused on searing, phase-modulated leads, percussive basslines and other-worldly effects!

A diverse palette of intermodulation and harmonic experimentation is offered through the Modulation Bus, its unique Waveshaper and the dedicated Thru-zero Phase Modulation Bus. An intuitive interface provides colour-coded visual feedback and responsive indication while performing in dimly-lit environments.

Two precision analogue oscillator cores

Precision, wide-range V/oct ramp cores, each ranging from deep subsonic to supersonic frequencies (ramp cores, and not triangular, deliver the ideal waveforms for analogue phase accumulation in the TZ-PM Bus)
Each core generates fundamental waveshapes which interact and mangle one-another through the complex Modulation Bus and TZ-PM bus
Simultaneous waveform outputs for each base shape
Dedicated button to toggle between RAMP or SAW for each core, inverting the phase of the ramp output
V/oct, linear FM and exponential FM inputs which are all independent of the TZ-PM functionality. The Carrier's FM occurs inside the core itself, separate from the TZ-PM bus.
DC-coupled linear FM

Carrier

The heartbeat of Mindphaser, focused on audio-rate generation. Drives the WAVESHAPER and TZ-PM bus. This core's frequency range spans the audible spectrum.

- An external hard SYNC IN forcibly resets the core, useful for punchy sequences, percussive basslines and drum synthesis -- or to sync to another VCO.

- Coarse and fine controls conveniently span the audible spectrum. Ranges further with external CV.

Modulator

An extremely wide range oscillator, spanning from deep LFO frequencies all the way up to supersonic sound! Four base waveforms and diverse internal routing options form a versatile palette of modulations for the CARRIER to feed on.

- Activating hard SYNC on the Modulator locks its core to the Carrier's heartbeat. The effect can be dramatic. Try this while phase modulating!

- Octave RANGE switch lets you quickly flick up and down between octaves. All the way beyond audio-rate and LFO speed octaves. Perfect for experimenting with different PM sidebands and taming the wide frequency range of the Modulator.

- Manual PW (Pulse Width) control and dedicated CV input for PWM.

Waveshaper

This isn't a classic waveshaper! Developed anew from the ground up, this waveshaper is focused on deep harmonic experimentation and audio obliteration. Each waveshaper parameter is capable of being "turned up to 11".

FOLD up to 5 octaves above the fundamental Carrier frequency. A ceiling forms at maximum, imparting additional harmonics.

FEEDBACK the waveshaped and phase-modulated audio through a signal path internal to the waveshaper.

AMPLITUDE modulation spans thru-zero, allowing for full-range ring modulation effects with bipolar CV or audio signals.

CLIP the final stage of amplitude with the switch to introduce a last stage of harmonics before the complex signal exits through the final OUT.

Switchable inverting attenuators on each CV input, for quickly inverting the behaviour of your modulation. The indicator illuminates red to tell you the attenuator has been inverted.

Two distinct waveshaping modes

A press of the shape switch toggles Mindphaser between RAMPOID (green) and TRIANGULAR (yellow) waveshaping modes.

These modes have a remarkable effect on the behaviour of wavefolding and overall character of the final complex OUT, in addition to TZ-PM Bus character.

RAMPOID mode folds more asymmetrically, with raucous, buzzing harmonic artefacts as you sweep and introduce TZ-PM

TRIANGULAR mode folds more symmetric, splitting the complex sine wave at its peak centre of the waveform. TZ-PM character is less raucous, and more smooth.

TZ-PM Bus

Thru-zero phase modulation in the ANALOGUE realm! Unlike its digital counterpart, analogue TZ-PM has its own character we've come to expect from analogue circuitry!

A dedicated, voltage-controlled phase modulation bus completely separate from the Mod Bus
Modulator's SINE wave normalled to the PM SOURCE input
SOURCE input allows you to modulate phase with any signal you patch in
Dedicated voltage-controlled INDEX (amount)
Manual phase lets you zero in (or not!) on the base phase before introducing modulation
Independent of the Linear FM circuitry in the Carrier core

Mod Bus

The internal modulation powerhouse, normally fed by the Modulator core, but external signals are patchable as well.

Select from the PULSE, RAMP/SAW or SINE output of the MODULATOR, or inject your own SOURCE to the bus.

Voltage-controlled INDEX behaves like a macro control when combined with various amounts and polarities dialled in at each CV destination.

Internal sends include the Carrier's classic Linear FM, Amplitude, Feedback and TZ-PM Index, with variable amounts and polarities!

Modulator waveforms internally feeding the Mod Bus behave unipolarly, for predictable modulation of every Mod Bus destination, without external patching. By patching in one of the Modulator's bipolar waveform outputs manually (or any external signal), you can override this behaviour.

Notes: SERRA generates a fully controllable 4 segment function (Attack, Decay, Sustain, Release) that can be adjusted in time with its own sliders and external CV inputs.

Tweak and modulate shapes until they fit your taste thanks to its onboard Attenuverter & Offset controls.

Tweak it further.

Nano Modules have made these built-in Attenuverter & Offset feature applicable to an external signal if connected to the SIG input, and then extracted via the OUT output.

Wide range.

As fast as 1 millisecond and as slow as 40 seconds. You can even improve this range by applying external CV to the selected stage.

Clear layout.

Accessible and comfortable to use, the controls are easy to handle and you can always see the envelope state through the built-in LEDs.

Notes: Dual tidal modulator with max, min & mix outs

FranKinksTides is a 18hp dual Tides (based on the Swirls pcb layout) with the max/min circuit from Kinks and some switches for sync, quadrature, pll and fm operation . It can be a double/complex oscillator, a dual function generator or any combination of oscillator, Lfo and Envelope generator with lots of cv control plus some interesting cross-modulation and sync features.

Some improvements in version 1.2:

-Mix output is now buffered, no signal bleeding on single outs.
-Mix pot controls also the balance of the signals sent to the max/min circuit.
-Uni/bi switch now also determines the signal sent to FM1.
-Clock/sync switch has now a center OFF position, no need of plugging a dummy cable in the Clock1 when using Sheeps firmware to avoid ultra fast sound bank changes.
small improvements for DIY:
-Bigger font size on the pcb.
-Parts renumbered for easy DIY.

Notes: TUL Dual Attenuator/-verter and Offset Generator

Temperature stable and accurate circuit design. The attenuator is exponential and can be regulated more precisely in the initial range.

As an attenuverter, the fader describes an S-curve, i.e. it is in Range +/- 0 finer adjustable. The AC gain is 1, so there is no loss at maximum Att/Attv settings.

The offset potentiometer shift by +/- 5 volts and can be switched to another mode on the back of the PCB using jumpers.

Here the attenuation is towards zero made until it is zero.

The normal mode leaves the voltage at the specified offset value.

Channel A is normalized to channel B so you can get two different CVs.

On the rear side of the PCB, you have a jumper to switch from offset pre fader (good for ADSR) and post fader.

Power consumption: +/- 20mA

Rackspace: 6HP

CV out is (-/+5Volt) if nothing is patched to IN A/B, so you can use it as a manual CV source.

Notes: The Erica Synths Black DADSR (Delay-Attack-Decay-Sustain-Release) is a fully analogue envelope generator that gives you extended control over events in your modular synth. It's a looping exponential envelope generator that has voltage control over each stage of the envelope. An independent Gate Delay section adds extra functionality to design advanced soundscapes, like delayed modulation e ects, wave morphing, etc.

Notes: The Serge GTO is a newly designed, complex multi-functional module which can be patch programmed to provide various slew and sample functions both for audio and CV signals, but also act as a (dual) oscillator or filter or bitcrusher or ... It is one of the essential Serge modules. The GTO is an offspring of the famous Serge SSG.

The Smooth section will place a positive and negative slew on input voltage transitions for lag effects, voltage controlled portamento and for low frequency filter applications. In Cycle-mode (cycle jack patched to the input), the Smooth side “will oscillate yielding a voltage controlled triangle wave LFO. A high level into the HOLD input will enable the Smooth Function to be used as a track-and-hold circuit with voltage controlled slew rate.

The Stepped function can be used as a sample-and-hold with voltage controlled slew rate limiting. In Cycle mode, a pulse applied to the Sample input will generate complex staircase waveforms for control voltage applications and for use as audio signals.

Each side has a temperature-compensated 1V/Oct input for use as an oscillator with a frequency range of up to 20kHz (left) and 8kHz (right). Each side tracks over 5 or 6 octaves.

The Coupler is an internal comparator which compares the output levels of the Smooth and the Stepped Generators. This output is useful for generating complex control voltages or random voltages.

Notes: The Quadigy is a complex envelope generator focused on live play.

The goal is to allow the user setting up rich, interactive and dynamically evolving envelopes without the risk of breaking up a subtle and intricate patch once on stage.

This is achieved by offering two main modes, one where full control is available and a Live mode where only the settings that are sensible using on stage are accessible.

The user interface offers an intuitive access for otherwise complex settings.

Advanced features such as automatic time-stretching, multiphase clocking and full morphing put the Quadigy in a category on its own.
