Synth modules

Notes: TriTone is a three section EQ plus saturator. Inner knobs control frequency and outer knobs control +- gain. All these sections Hi Shelf, Band Pass and Low Shelf are having + 20 db of gain and 30 db of reduction. Each section can work independently or they can be serially connected by the switches. Middle input in each section accepts CV for its frequency, so all three sections can be individually FMed by the external CVs.

If the inputs are fed with the modular level signals (+- 5V), then there is little room for "plus" EQ gains before saturation starts. In this case the input level should be attenuated first, if saturation is not desired and much "plus" gain is needed. Otherwise saturation drastically enriches the tone and the module works like very flexible overdrive FX.

When the switches are set to upper positions, then all three sections work independently. With the maximum gain reduction (CCW position) of the upper section (Hi Shelf) it becomes a useful kind of Low Pass filter. On the contrary - maximum gain reductions of the lower section (Low Shelf) makes it a High Pass filter.

Please note the internal routing done by the switches: the output of the uppers section is added to the input of the subsequent lower section. If nothing is connection to this lower sections' input, then only the upper section's output is processed. This makes it a 3 band EQ with the switches set to lower position. Having separated inputs opens up more possibilities over ordinary EQs.

Notes: Alan (micro Turing Machine) Shift Register Based Sequencer

The randomness of the Music Thing Modular Turing Machine, shrunk down to 6HP. Alan retains all of the same functionality as the original including the connectors for the expanders.

While this module has little to do with the original Turing Machine (by Alan Turing), it is a shift register based sequencer. You cannot program this sequencer, instead it builds random sequences that can be locked in.

Alan comes tested, calibrated and ready to bring random voltages.

The After Later Audio panel is black and gold and made from FR4. The package will include a power/ribbon cable and a one year warranty.

Notes: uBurst

This is a new build of the micro version of Mutable Instruments Clouds. The module retains all the functions of the original Clouds, taking up significantly less rack space.

These modules use tall bushing potentiometers to offer a more stable feel.

The module is fully assembled, tested, and calibrated. Eurorack power cable is included.

Notes: Erica Synths Black VC Clock is the beating heart of your modular system.

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: The Erica Synths Black Low Pass VCF is designed for analogue purists, who take sound design seriously. It's highly stable, 24dB/oct resonant low pass VCF with voltage control over cutoff (two CV inputs, one is with an attenuverter) and resonance. Bonus features are built in post-filter overdrive circuit with user adjustable drive amount and the Black Filter Coupler connector.

When used in combination with the Black High Pass VCF and the Black Filter Coupler, you get a Holy Trinity of VCFs for an ultimate analogue modular system.

Cutoff

This is the main control of the module - manual cutoff frequency adjustment. The incoming CV is added to the cutoff knob position.

Drive

For extreme results, flip the drive switch on! This will apply post-filter drive. You can preset drive level to your taste by adjusting a trimpot close to the switch on the back side of the module.

Reso CV In

This is the resonance CV input.

In Level

Adjust the audio signal level.

Resonance

Adjust the resonance level manually. On settings over 1PM the filter will start to self-oscillate. The incoming CV is added to the resonance knob position.

CV1 Level

This is cutoff CV attenuverter. Adjust the CV level to your taste!

ResoCV Level

Adjust the resonance CV level to your taste.

CV1; CV2
These are the cutoff CV inputs. The CV1 level is adjustable by CV1 LEVEL attenuverter knob, CV2 is applied to the cutoff without attenuation.

The Black Low Pass VCF has a hidden feature - the Black Filter Coupler connector. The Erica Synths Black Filter Coupler is a satellite module for the Black High Pass and the Black Low Pass VCFs, and it adds versatile Bandpass and Band Reject filter functionality to your modular system.

Please note, that the Black Filter Coupler works only with Erica Synths modules and you need both Black High Pass and Low Pass VCFs.

Remove the jumper and connect the Erica Synths Black Filter Coupler. 2x5pin ribbon cable is supplied with the Black Filter Coupler module. Use this trimpot to adjust post-filter overdrive to your taste.

Notes: A warm and deep sound source you can rely on

A flexible and warm Analog Multifunction Oscillator, rich in harmonics. Excellent for performance use!

ONA can work as an Audio Oscillator or as a Low Frequency Modulator and it provides control over all its parameters, making it a versatile, deep and easy-to-use oscillator.

Thanks to its triangle-core oscillator and wave-shapers you can choose between a big palette of output waveforms to give shape to your ideas.

Classic Waveforms. Sine, Triangle, Saw and Square.

2 Complex Waveforms with Pulse Width Modulation.

2 Sub-Waveforms to add some bass sounds easily.

Blend them to give unlimited depth to your sound!

Notes: The Erica Synths Black Ring-Xfade is an extremely versatile module for sound shaping. It consists of two unconventional ringmodulators/waveshapers, a crossfader that works both for audio and CV and a VCA. Unlike conventional ringmodulator that works only with a signal present on both signal and carrier inputs, the Black Ring-Xfade passes through the signal without alteration, if no carrier is present, but low level signals on the carrier input result in unique waveshaping. Add the crossfader between two ringmodulators (or as a separate unit) topped up with the VCA, and you have an amplitude modulation powerplant in 10HP!

Ring1 CV; Ring2 CV
These are the ringmodulator carrier (CV level) level controls. Unlike conventional ringmodulator, this one passes signal unaltered, if RING CV is turned down. With increasing Ring CV level a slight waveshaping turns into proper ringmodulation.

Xfade
This is a manual Crossfade control. This fades smoothly between signals patched into XFADE IN1 and XFADE IN2. The XFADE CV is added to the knob position.

Coupling
Set the Crossfader mode - AC is optimized for use with the audio signals, DC - for control voltages (but it will work fine with audio, as well).

Ring 1; Ring 2
The green LEDs give visual feedback on signal levels, applied to XFADE IN1 and XFADE IN2 respectively.

Vol CV
Select the VCA CV response. A 0-10V setting is intended for use with the envelope generator, a -5V - +5V setting - for nice tremolos with a LFO.

Xfade IN1; Xfade IN2
These are the Crossfader inputs. They are normalled to the Ringmodulator ouputs, so, if nothing is patched here, you can crossfade between two ringmodulated signals.

Xfade CV
This is the Crossfader CV input. The CV is added to the XFADE knob setting.

VOL CV
This is the VCA CV input. The VCA is post-crossfade - it controls the amplitude of a resulting signal after the crossfader. It will also work with low frequency control voltages applied to the XFADE Ins - nice for designing unconventional modulations.

Ring1 Out; Ring2 Out
These are the ringmodulator outputs.

Xfade Out
This is the Crossfader output and the main output of the module.

Ring2 In; Ring2 CV
These are the second Ringmoduator signal and carrier inputs respectively. These two are normalled to the RING1 inputs, and if no signal is patched here, the duplicate the first Ringmodulator. Interesting trick is to set RING CVs at different levels and crossfade between two ringmodulator signals.

Ring1 IN; Ring1 CV
These are the first Ringmoduator signal and carrier inputs respectively.

Fade L; Fade R
The red LEDs indicate the crossfader position.

Xfade CV LVL
This is a crossfade CV level attenuator. By adjusting it you can control a span of fading between inputs.

Notes: Really nice stuff here. The filter circuit from ADDAC's 4 Voice Cluster module gets reimagined as a multi-mode stereo or dual mono filter module. A lot of filter action in just 6hp.

Supplier's Notes:

While developing the ADDAC105 4 Voice Cluster module, a new multimode filter to place after the summing mix stage- and the results were so postitive that it was released as a dedicated filter.

To make it more interesting, the circuitry was duplicated, to be able to use it in a stereo signal path.

To make it more versatile, a switch was added to set the working mode from Stereo to Dual Mono where both filters can be used independently.

In Stereo Mode the Left Cutoff is used to control the Right Cutoff.
In this case the Right Cutoff Knob and CV Input are simply bypassed and will have no impact on the Right Channel operation.
This allows immediate sync of both filter frequencies when the Stereo position is engaged.
Optionally there's a jumper in it's back that, when placed, connects the Right Controls back to the Right CV control allowing the possibility to control the offset of the Right Channel Cutoff.

Resonance is independent on both Modes and still has to be set manually to match both channels.

Both the Audio and CV inputs are normalled from the Left into the Right channels.
As standard plugging any input to the Right channels removes this connection.

Notes: For decades, the voltage controlled slew limiter has been a staple of modular synthesisers. With its extreme versatility, it can be used to slew control voltages (CVs), create envelopes, as a low-frequency or audio oscillator and much more.

Today, Contour 1 brings a fresh approach to this classic circuit. It delivers much improved performance and control by incorporating modern design techniques.

At its most basic, a slew limiter slows down the rate of voltage change in a signal. On Contour 1, the rising and falling rates can be individually set using sliders and CV modulation.

The gate and trigger inputs allow the module to be used as a function generator: create snappy attack-release (AR) and attack-decay (AD) envelopes, with slope times ranging from 500 us to 30 seconds. The dedicated gate input makes it easy to generate +10 V envelopes from any signal source. Using the large tactile push button, AD envelopes can be manually triggered. A trigger will also reset the output voltage.

When set to loop mode, Contour 1 will continually re-trigger itself. In this mode, it fulfils the role of a variable-shape low-frequency oscillator (LFO) or temperature-stable voltage controlled oscillator (VCO) in the audio range.

Both the rising and falling slopes can be individually bent, from concave through linear to convex. While doing so, the deviation in slope time, and thus oscillation frequency, is kept to a minimum. Since the bend parameters are separately voltage controllable, boundless modulation possibilities present themselves.

Explore anything from shape-shifting envelopes to rich VCO timbres: Contour 1 will make you re-think what a slew limiter can do.

Notes: Clever four-channel utility module designed to make it easier to achieve perfect oscillator tracking and transpose CV signals. Also includes some neat quantising and portamento features.

Supplier notes:
The CalTrans solves issues encountered when playing tonal music with a modular system: tracking problems, curves unrelated to Volt per octave ratio, limited octave range, cumbersome transpose, ...

The CalTrans corrects and expands the range of troublesome VCOs and brings V/Oct tracking to anything that oscillates.

Besides calibration, the CalTrans offers live play features. Each channel can be quantized and any combination of them transposed jointly.

A pair of rotary encoders with detent allow an precise selection of octaves and semitones.

VCOs whose tracking doesn't go high enough to follow the leader will see their pitch repositioned in their highest possible octave so that the global harmony is unaffected.

You can add a pinch of portamento and glissando to each channel and save the whole in user presets.

Notes: Row Power is a clean, regulated, and protected power solution for eurorack systems. Row Power 35 provides 35W of power, suited for any typical eurorack row (84HP to 168HP):

+12V @ 1.4A
-12V @ 1.25A
+5V @ 1.0A

Simply plug a universal power supply (laptop style) into either of the barrel plugs on the 4HP panel. Connect your modules via flying-bus cables or the Bus Stick.

Daisy-chain multiple Row Powers to use a single power brick for multiple rows (typically 3-5 rows per power brick). Each row will be independently regulated and protected for ultra-low cross-talk between rows. Rows can also be hot-swapped (plugged/unplugged without powering the whole system down).

Notes: Outs enables your modular system to output both professional and prosumer compliant audio, and send it to external amplifiers, mixers, recording devices, or DAW interfaces. Using the L+R Level knob, it scales modular-level voltages down to the level required to drive external gear at either the +4dBu balanced professional line-level standard or the -10 dbV unbalanced standard.

Headphone monitoring is also provided via a low noise built-in headphone amp (with its own independent level control), capable of driving a wide range of impedances - from studio grade headphones to portable style earbuds.

To use Outs, simply connect the final output of your patch to the 1/8" inputs (where the built-in activity LEDs light up to indicate the presence and intensity of the input signal). The left input is normalled to the right, so you can create a stereo signal from a mono source. Or if you have an Intellijel Mixup, you can remove a jumper from its rear panel, and connect it to the Outs module using the 3-pin link cable included with the Mixup.

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: EME (Eloquencer MIDI Expansion) is the perfect companion for the Eloquencer, adding capabilities to sync with MIDI devices, control most of the eloquencer parameters with MIDI interfaces, generating MIDI voices from the eloquencer tracks, and converting MIDI signals to the eurorack world.

Description:
MAIN FEATURES
IN / OUT
DIN-5 MIDI Input, DIN-5 MIDI Output, USB Host.

BUTTONS
4 freely assignable buttons. They can be assigned to:

Next/previous pattern
Next/previous part
Direct access to Pattern mode, Play parts, Duplicate, Project, Gate REC, CV Key REC, MIDI key REC, Free Play...
Save current project
Random 1 to 3 layers of selected track
Reset LFO of selected track
On/Off LFO of selected track
Freeze
Revert
Fill A to H or selected track
Mute A to H or selected track
DJ Nudge FWD/BCK fine/coarse

MIDI CLOCK
Eloquencer can receive 24ppqn sync from MIDI device from its DIN-5 MIDI Input, and can send 24ppqn MIDI clock through its DIN-5 MIDI out.
When working as 'internal' it will send the internal clock to the MIDI output.
When working as 'external' will send the eurorack incoming clock to the MIDI output transformed into 24ppqn.

MIDI OUT
The Eloquencer tracks can be independently assigned to:
- Voice events (note on/off, velocity, ch pressure...) For example Track A can be assigned to Channel 1 Note on/off and Track B can be assigned to Channel 1 Velocity, so track A gates and CV control Channel 1 notes and pitch, and track B controls Channel 1 Velocity.
- Control Change (CC)
- Program Change (PC)

The gate and CV output will work as usual when a MIDI OUTPUT is assigned, so voices can be doubled using the modular and an external synth.

There's a particular execution order for MIDI out events, so the first to be launched is the Program Change, followed by the CC and then the voice events. This way, we can launch program changes before the note on message is received allowing preset changes for each step.

MIDI IN
Both, the DIN-5 MIDI in and the USB can be used to change eloquencer parameters using controllers or to introduce notes in REC MODE using a keyboard.

There are 3 different groups of controls associated to MIDI channels:
- Channel : 8 MIDI channels to control parameters of specific tracks from A to H
- Global : 1 MIDI channel to control Global parameters.
- Focus: 1 MIDI channel to control the parameters of the currently selected track (track in focus). That means that if Track A is selected and we send CC 38, we will be shifting track A, but if we select track B and we send the same CC 38, we will be shifting track B.

When using the USB host input, the EME can send feedback information in case the controller that is being used has LEDs to be updated.

There is a big amount of eloquencer parameters that can be controlled using an external MIDI interface / controller. For example:

Non-destructive track parameters addition/subtraction (CV, CVP, CVR, GL GLP, R...)
Track length
Step mode / Step mode DIV / Step mode REP
Track shift
LFO on/off / Type / Length / amplitude.
Fill
Mute
Random
CV Gate link
Scale group and root
Tempo
DJ Nudge
Shuffle
Clock out
Play / Stop
Direct access to modes (Pattern, Project, Live REC...)
MIDI INTERFACE

A MIDI Channel can be assigned to an Eloquencer Track, so the gate and CV outputs will stop listening to what is sequenced and start listening all note on/off messages coming from the chosen MIDI channel.

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: Row Power is a clean, regulated, and protected power solution for Eurorack systems. Row Power 45 provides enough power for two to three typical Eurorack rows (typically up to about 312HP):
+12V @ 2.0A maximum, 1.5A recommended
-12V @ 1.4A maximum, 1.2A recommended
+5V @ 1.5A maximum, 1.2A recommended

Simply plug a universal power supply (laptop style) into either of the barrel plugs on the 4HP panel. Connect your modules via flying bus cables or the Bus Stick. For custom power systems, the Row Power 45 has a set of easily soldered holes for using large gauge wire or MTA156 connectors to connect to distribution bus boards.

Multiple Row Power modules can be powered from a single power brick by daisy-chaining with an inexpensive barrel cable. The Row Power 45 can also be daisy-chained to 4ms Company's Pod enclosures. Each power supply is independently regulated and protected for ultra-low cross-talk between rows/pods.

The Row Power 45 is compatible with the 4ms Row Power Shield. This device (sold separately) attaches to the back of the Row Power 45 and monitors the amount of current being drawn, as well as the voltages of the power rails. The information is sent over Bluetooth to be displayed on a phone or tablet.

Notes: Stereo Strip takes the idea of a channel strip and makes it modular. By bringing this long-established component of the audio engineering world into the Eurorack environment and by adding CV control over its key parameters, you will find new, creative ways to use it in your patches!

It features stereo inputs and outputs for audio or CV with EQ, voltage controlled panning, stereo VCA, performable mute and input/output level switching for Eurorack or line level uses. Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.

Stereo Strip was designed to be a creative part of a modular patch. Creating stereo images from mono sources, shaping and modulating existing stereo images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.

The addition of line level gain boosting (for the input) or reduction (for the output) allow it to work as a stereo input or output interface for external gear with the advantage of the VCA, panning and the EQ to shape the sound. Experiment with bringing external gear into the Eurorack format and then shape and modulate those sounds them on the way in!

Try patching Stereo Strip anywhere you would place a VCA in a system and/or explore its EQ and voltage controlled panning, which are rarer additions to the sound sculpting options for the Eurorack format.

Notes: Transit has two stereo (dual mono) channel lanes of audio with an all-analog signal path. Each stereo channel lane has its own input gain control, mute button and ducking input. The Ducking input on each channel operates like traditional side-chaining on a compressor where an input signal, CV or Trigger input (i.e. LFO, Clock, Gate) modulates the gain reduction of the audio.

Transit offers a main stereo output controlled by the master volume control knob and an independent 3.5mm headphone output controlled by its own headphone level control knob.

Digitally controlled LEDs for master indicates level via white and pink illumination while each channel lane illuminates the LEDs with the color red when engaging mutes.

All in all, Transit is a rather full features compact 6hp dual stereo channel lane eurorack formatted mixer that offers easy signal mixing, gain staging, ducking, and performance-oriented mutes. Transit is just as at home in a small eurorack system as one Transit or several would be in a larger system.

Transit pairs perfectly with Per4mer and a Modbap20 compact powered Eurorack case. It also pairs well with Osiris and any other module that could benefit from a compact analog dual channel stereo ducking mixer, sub mixer or final output mixer.

Notes: Make quick changes to signal routing manually or with CV control. Any audio or CV signal can be routed via two outputs in series, parallel or reverse series. Quick, clever and easy to use.

Supplier's Notes:
Signal flow is an essential concept in modular synthesis: the path taken by audio or control voltages (CVs) may be long or short, branching or linear, intuitive or highly complex.

While the patch programmability of a modular system is its greatest strength, it can also be a weakness: quick experimentation is often hampered by the need to repatch the synthesiser to change the signal flow.

Pivot 2 offers a unique solution: a compact, fully voltage controlled variable signal router. At the turn of a single knob, any signal can be routed through two external modules in series, parallel or reverse series, as well as any combination in between.

Notes: MIXZ is a multi-channel mixing module for mixing audio, CV, and gate signals with excellent linear response and low noise. Balancing a clear visual layout and multiple mixers in a small footprint makes the MIXZ easy to use in a variety of configurations within a modular synth. Its high-quality analog mixing circuitry makes for a great sounding mixer with plenty of headroom, providing a smooth, organic merge of dynamics and excellent separation of mixing sections and channels. MIXZ has three sections:

Mixer A: a low-noise, 4-channel mixer with independent gain control for each channel.
Mixer B: a low- noise, 4-channel mixer with master gain control.
MixBus: a multi-channel mixer that mixes signals from modules utilizing the Tiptop MixBus.

Mixer A and B can be configured as either two independent, 4-channel mixers or as a single 8-channel mixer. If the output of Mixer A is not in use, then Mixer A will be routed internally to Mixer B forming the 8-channel mixer.

Tiptop MixBus is a new method we have developed to mix audio signals through the Eurorack power bus board without patch cables. A little bit of magic, eh? Although this technique is not ideal for a low-noise mix, we found it to be useful for some applications, including mixing our drum modules, which all have a MixBus-enabled output. The result is that your drum modules are always available and mixed on the master out of the MIXZ with a flip of a switch. This will save you time and frees up cables for repatching sound again and again, while keeping the channels of MIXZ free to bring other signals into the mix.

Combining the MixBus with Mixer A and B, the MIXZ sums dozens of channels in only 10HP.

Notes: XFADE 1U is a classic DJ-style stereo crossfader, with a few extra tricks up its sleeve. The 'A' and 'B' sides both have L+R inputs. The crossfader blends two stereo input signals together - crossfading one into the other depending on the position of the slider and the selected XFADE Shape. The blended output appears at the MIX L and MIX R output jacks.

In addition, XFADE 1U can be used as a modulation source for controlling other modules, since the crossfader also outputs control voltages from the CV A and CV B jacks. A switch determines whether these voltages are unipolar (crossfading from 0V to 5V; and 5V to 0V), or bipolar (crossfading from -5V to +5V; and +5V to -5V). The two LEDs indicate the polarity and relative levels of the CV A and CV B signals.

XFADE 1U uses a precision Innofader crossfader submodule, with moving capacitance technology for smooth and precise control. This is the same part found on many high-end DJ mixers.

Features:

Smooth and ultra-low friction Innofader Mini-Innofader module with moving capacitance technology
Stereo or Mono operation
DC coupled inputs and outputs

Notes: Part of Xaoc's Leibniz subsystem, which processes signals and voltages by manipulating binary 8-bit numbers, the Poczdam allows switching between two data sources.

Supplier's Notes:
Poczdam is a binary data routing solution for the Xaoc Leibniz Subsystem. It facilitates manual and remote switching between two Leibniz data sources, modifying individual bits of the data stream, and re-clocking the data with its onboard voltage-controlled wideband oscillator or any external clock signal. Poczdam is particularly useful within complex Leibniz setups where the user needs to reconfigure the data flow between multiple modules. However, it can also be employed in small creative patches, e.g., for waveform splicing, disrupting rhythmic loops, or generating digital chaos.
To better understand the device and avoid common pitfalls, it is strongly advised to read through the entire user manual before use.

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).

Notes: Module A-147-4 is a dual voltage controlled LFO (Low Frequency Oscillator). Each LFO has the five waveforms triangle, sine, rising and falling sawtooth, as well as rectangle available. The rectangle output features manually adjustable pulsewidth and pulsewidth modulation by means of an external control voltage. The core waveform is triangle. The other waveforms are derived from triangle by means of waveform converters. The frequency of each LFO can be adjusted manually and modulated by means of an external control voltage with associated attenuator and polarity switch. By means of a jumper the basic frequency range of each LFO can selected: about 0.02 Hz (~ 50 seconds) ... 2.5kHz or about 0.0017 Hz(~ 600 seconds) ... 220Hz. That way each LFO can be used also as a VCO with a max. frequency of about 2.5kHz. Each LFO features a reset input which can be used to reset the triangle signal.

The module has these controls and in/outputs available:

Control F : manual control of the frequency, for each LFO the frequency range can be selected by means of a jumper from two values (see technical notes)

frequency coverage of control F in the high frequency range: about 0.075 Hz (~ 13 seconds) ... 1,4kHz

frequency coverage of control F in the low frequency range: about 0.007 Hz (~ 140 seconds) ... 125Hz

Control CV: attenuator for the signal applied to the CV socket, by means of a jumper a small positive voltage can be applied to the switching contact of the /CV/ socket, as long as no patch cable is connected to /CV/ socket the CV control then works as fine control for the frequency

Switch CV Pol.: polarity switch for the signal applied to the socket /CV/

Control PW/PM: combined control for manual and CV control of the rectangle pulsewidth:

when no patch cable is connected to socket /P/ the control is used to adjust the pulsewidth (PW) manually

when a patch cable is connected to socket /P/ the control works as attenuator for the external CV signal with a basic pulsewidth of 50:50.

Socket /CV/: frequency control voltage input, in the factory the module is adjusted so that the sensitivity of this input is exactly 1V/octave when the CV control is fully CW.

Socket /R/: reset input, according to the associated jumper the reset input is edge triggered or level controlled (see technical notes for details)

Socket /P/: pulsewidth control voltage input

Sockets with waveform symbol: output of the waveform in question (triangle, sine, rising and falling sawtooth, rectangle)

The output voltage ranges are about -5V ... +5V (10Vpp), except the rectangle output

For the rectangle output one can choose by means of a jumper if the range is about -5V ... +5V or 0...+10V.

LED: visual control of the LFO (triangle)

The inputs of the module are labelled with white characters on black background (in the text included into two slashes). The outputs are labelled with black characters.
Technical notes and special features:

The basic frequency range of each LFO can be selected by means of a jumper. The settings correspond to two different capacitor values for the VCO circuit. The relation between the two ranges is about 1:11. When the upper range is selected frequencies from about 0.02 Hz up to 2.5kHz can be generated. For the lower range the values are about 0.0017 Hz ... 220Hz. To obtain these full frequency ranges external control voltages are required. With the frequency control F only the frequencies mentioned above are possible.

Apart from that the range for the manual control F can be reduced to obtain a finer resolutuion. For this a jumper has to be removed. The range of control F is then reduced to about 1:4.5 only.

In the factory the starting voltage of the triangle output after a reset is adjusted to 0V, i.e. the triangle starts from 0V with the rising slope after a reset. By means of a trimming potentiometer the starting voltage can be adjusted to another value (e.g. to -5V).

Another jumper is used to set the reset behaviour to edge triggered or level controlled. When set to edge triggered the rising edge of reset signal is used for the reset (independent of the duration of the "high" state of the reset signal). When set to level controlled the triangle output remains at the starting voltage as long as the reset signal is "high". Only when the reset signal turns "low" the triangle starts.

Notes: Module A-135-5 is a combination of a voltage controlled polyphonic mixer and a polyphonic suboctave generator. It is made of 12 voltage controlled amplifiers (VCAs) which are arranged in form of a 4x3 matrix. Herewith up to three four-voice polyphonic signals (e.g. the outputs of three polyphonic VCOs A-111-4) can be mixed. The level of each of the three polyphonic channels (A, B, C) with four voices each can be controlled manually or by means of an external control voltage with associated attenuators.

In addition the module features four frequency dividers which derive the suboctaves from the four input signals of channel A. The suboctave signals are wired to the switching contacts of the sockets of channel B. As long as the sockets of channel B are not patched the suboctave signals of channel A are used as inputs for channel B. The suboctaves are symmetrical rectangle waves with half the frequency of the corresponding signal A. For example two polyphonic VCOs A-111-4) can be used and patched to the channels A and C. Channel B then provides the suboctaves of channel A.

As the module is fully DC coupled it can be used also for the mixing of control voltages in a polyphonic environment (e.g. for envelopes, LFOs or other control voltages).

The switching contacts of the 12 input sockets and the four outputs are internally connected to pin headers. That way the module can be internally pre-patched to other polyphonic modules (e.g. the four inputs A to an A-111-4, the four inputs C to another A-111-4 and the outputs to the polyphonic filter A-105-4). As the switching contacts of the sockets are used for the internal pre-patching the internal patch can be overridden by using the sockets at the front panel.

The module has these controls and in/outputs available:

Controls Lev.A, Lev.B, Lev.C: manual level adjustment of the channels A, B and C

Controls CV A, CV B, CV C: attenuators for the corresponding control voltage inputs

Sockets A1...4: inputs channel A

Sockets B1...4: inputs channel B (if the sockets are not patched the suboctave signals are used for the inputs B)

Notes: For anyone who has ever struggled with finding their way around a Eurorack synthesiser on a dark stage or a dimly lit studio, Dim 2 presents an illuminating experience. In just 4 HP, it provides a complete solution to upgrade your modular system with a pair of dimmable console lights.

The high-efficiency PWM dimmers run at high frequency, ensuring flicker-free and noise-free operation. Additionally, extensive line filtering keeps your Eurorack power supply happy and clean.

Not limited to just manual control, both dimmers also feature control voltage (CV) inputs, turning the connected lamps from simple light sources to voltage controlled audio-visual spectacles.

While the use of the included BNC LED lamps is recommended in order to keep power consumption low, halogen lamps may be used as well. Provided your power supply is beefy enough, up to 6 W of power may be drawn from each output. This even makes it possible to drive 12 V LED strips, truly making your patches shine bright.

Notes: ADDAC711 is a dual channel Isolated DI box and is all about keeping the sound coming into your Modular free from any undesired noisy interferences, making sure that what you're getting from your inputs is what your external hardware is actually producing. It provides galvanic electrical isolation between the Modular system and external sources preventing impedance mismatch and ground loop induced hum. ADDAC's 711 circuit is designed around a unity 1:1 type Low-cost Audio Transformer operating in the 20 Hz to 20 KHz range, this impedance matching transformer provides two fully balanced outputs (via XLR connectors).

There are two independent channels on the module with:
Audio Output
Signal overload warning led
LIFT/FLOAT/GND toggle switch
Gain control
XLR Input

The LIFT/FLOAT/GND 3-way switch lets you choose between lift, ground or floating ground. In the LIFT position (left) the module circuit will be "lifted" to ground through a 100R resistor and a 10nF capacitor. In the FLOAT position (middle) Ground will not be shared leaving ins and outs grounds completely apart from each other fully isolating both signals.
In the GND position Ground will be shared between inputs and outputs, here no isolation is used. Any of these three positions may be the best form of avoiding ground loops or any other undesired interference occurring between your modular and the external hardware. Try out which one of these options will work best in any given situation.

The importance of using Audio Transformers

Applying a transformer balanced input isolation has lots of advantages over other less expensive ways for dealing with ground loop issues. This method provides the chance to set a very simple and cleancircuit in which the signal transfer process develops smoothly and humming free. The transformer is a device that performs both signal balancing and high-to-low (or vice-versa) impedance conversion, while rejecting straggled DC voltage and Radio Frequency Interference from signal passing through a magnetic bridge. In a transformer, two (or more) coils (called windings) of insulated wire wound around a magnetic metal core allow for its input(s) and output(s) not to be physically connected together. When an AC signal passes through the input winding (the primary), a perfectly related AC signal appears on the output winding (the secondary). This way, by the fact that signal flows via inductive coupling between the two windings of the transformer, this module presents a most accurate electrical isolation between its input and output. A same number of windings on each coil guarantees that there's no gain loss when audio signal passes from the primary to the secondary windings. Furthermore, since these two windings are insulated from each other, the transformer will electrically isolate ADDAC711 from any other device, preventing hum problems coming from an outsider ground. Being a low-cost transformer the frequency response curve is not completely linear, still the -0.2dB
attenuation at 50Hz feels negligible.

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: Verb is a lush stereo reverb with a full feature set and superior audio quality. A wide range of reverb times take your sound from small room to never-ending concert hall.

CV over mix allows dynamic movement between the dry and reverberated sound, and the dampening control lets you dial in the perfect timbre for the wet signal. Whether you need a traditional reverb for an FX send or an esoteric sound design tool, Verb can take you there. Get lost in space with Verb.

Notes: Module A-108 is a completely new voltage-controlled low pass filter based on the well-known transistor ladder (Moog ladder). The module has internally an 8-stage low pass filter with different slopes available: 6, 12, 18, 24, 30, 36, 42 and 48 dB per octave. In addition, it features a band pass output (i.e. band pass with transistor ladder). In the factory, the 4 low pass outputs of the A-108 are internally connected to the filter stages 6, 12, 24 and 48dB.

Resonance (Emphasis or Q) can be adjusted manually right up to self-oscillation, in which case the filter will behave like a sine wave oscillator. The A-108 features an external feedback input that enables the insertion of additional modules into the feedback path (e.g. VCA for voltage-controlled resonance or phaser/frequency shifter for phase/frequency shifting effects). The socket is normalized and internally connected to the 48dB low pass output if no cable is inserted into the feedback socket.

The frequency can be adjusted manually, or by voltage control. Three CV inputs (CV1, CV2, CV3) are available. CV2 and CV3 are equipped with attenuators.

The filter audio input is very sensitive so that distortion - if desired - is possible even with normal A-100 levels (e.g. VCO output). Self-oscillation will break off at high distortion levels as the internal feedback signal is drown out by the distorted audio signal. This feature may intentionally be used to create new sounds.

In combination with the Voltage Controlled Mixer A-135 and the Morphing Controller A-144 a filter with voltage-controlled slope can be realized (i.e. controlling the slope from 6dB to 48dB via CV).

Notes: Module A-150-8 contains eight manually/voltage controlled switches. Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2). The switches are bi-directional, i.e. they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. Two LEDs show which in / output is active (i.e. which is connected to the common out / input). In addition, the LEDs are used for the programming of the module:

For each unit the operating mode can be selected: Toggle or Level controlled. In Toggle mode the rising edge of the CV input or operating the manual control button changes the state of the switch. In Level mode the switch state is defined by the voltage applied to the CV input (low voltage = I/O1, high voltage = I/O2) or by the state of the manual control button (not pressed = I/O1, pressed = I/O2). The modes are programmed very easily: Operating the Toggle/Level button of the program section displays the current state of each switch with the LEDs: left LED on = Toggle mode, right LED on = Level mode. Operating the manual control button of the switch in question changes the toggle/level mode while the Toggle/Level button of the program section is operated. During the programming patched CV signals may have to be removed as the CV signals would interfere with the manual operating buttons during the programming process.

In addition, it's possible to define master/slave groups. In such a group the upper unit (= master) controls also the state of the following switches provided that they are defined as slaves. Master/slave programming is also very simple: Operating the Master/Slave button of the program section displays the current state of each switch with the LEDs: left LED on = Master, right LED on = Slave.

When all 8 units are defined as master all switches are independent from each other. If for example the sequence is MSSSMSMS the control unit of the first switch also controls the switches 2, 3 and 4. The control unit of switch 5 also controls the switch 6, and the control unit of switch 7 also controls the switch 8. The current states of the slave switches are overwritten by the state of the master switch.

Technical note: To protect the electronic switches in case of an unsuitable patch (e.g. connection of two outputs) a 1k protection resistor is inserted into the O/I line of each switch. If control voltages used for VCOs are switched this may cause a small voltage drop and lead to undesired audible detuning. For this application we recommend to insert a CV buffer between A-150-8 and the VCO(s), e.g. the Buffered Multiple A-180-3 or the Precision Adder A-185-2. Integrating the buffers into the module A-150-8 was not possible because this would ruin the bidirectionality of the switches.

Notes: 'MUM M8' is an 8hp Eurorack low pass filter building on the filter design used in the classic Akai S950 12 bit sampler with the addition of resonance, voltage control, clipped saturation and a dedicated VCA.

The low pass filter gives the recognisable super smooth vacuum like tone sucking sound which works magic on complex sources. The addition of clipped overdrive and intentionally aggressive self-oscillating resonance compliment the smooth filter core by juxtaposing it into more wasp like territory with acidic squeals and a more gritty sound.
Mum M8 features dual voltage control with attenuation (and inversion) of filter cut off and voltage control of resonance together with dual audio inputs - one of which includes a VCA to with the capability to aid overdriving signals into the filter core.

The filter core is a 6th Order Butterworth switched capacitor type design featuring an analog core but controlled by a high speed digital clock. This produces the characteristic smooth sounding filter but, as with the original S950, has a relatively high minimum cut off as to avoid 'clock bleed' into the filter output from the digital control. This minimum cut of point (and introduction of bleed if required) can be controlled via trimmers on the rear of the module (see calibration chapter). It is not unusual for there still to be some low-level artefacts from the clock present, particularly during filter sweeps - these add to the filters character.

The motivation for the module came from discussing filters in classic samplers with the artist Jack Adams - aka Mumdance. Jack suggested investigating the S950's filter well known as for it use in classic use in early jungle and hardcore. From that point onward Jack provided inspiration, help and feedback in the development of the filter. Big up Mumdance.

Notes: This useful module is a Bipolar Mixer, DC voltage source and Linear DC coupled VCA.

- With no input to channel 1 the Input 1 pot becomes a voltage source with a range of +/- 6V.
- The control pot and input for channel 4 can be switched to become an offset control and/or a second CV input for the VCA.
- Input 3 has 2x gain, so it can amplify lower level CV's too.
- All inputs are bipolar, which means that either non-inverted or inverted version of the input signal can be added to the mix depending upon the Input control being turned clockwise (non-inverting) or anti-clockwise (inverted). The 12'o'clock position is zero.

Notes: The Quad VCA is a compact and feature packed module that is sure to find its way it almost all of your patches. In addition to being used for standard VCA duties it can also be used as a mixer and signal booster.

Features:

- Manual LEVEL control per VCA which is convenient when using the module as a mixer or for biasing when CV modulating the VCA with a bipolar LFO.
- Dedicated CV attenuators with dual colour LEDs for monitoring bipolar CV signals.
- Continuously adjustable response from linear to exponential per VCA.
- Each CV input is normalled to the adjacent one for cascaded control.
- Each output is normalled to the mix input of the adjacent one which allows you to use adjacent sets as submixes or the fourth output can be used as a master mix output when none of the other outputs are patched.
- Each VCA has a boost switch that increases the output level by approximately +6dB (double).

Notes: The Shifty is essentially a combination of four sample and hold stages, a sequential gate and sequencer controller. This collection of functions allows for some specific and useful utility application.

One of the primary uses for Shifty is to take a monophonic sequence source and route each new note of the sequence to up to four different synthesizer voices in a specific pattern. In this way you can create pseudo polyphonic sequences since each voice can be triggered to play and sustain while the next voice int the sequence gets triggered. Another term for this is hocketing.

The other main application of the Shifty is to function as an Analog Shift Register. In this mode each new gate input received causes the current set of pitches to be shifted to new output locations as a new one is added and the oldest one is replaced. This can be an interesting way to create chords that are up to four stacked notes when used with a pitch sequence source that has a harmonious series of notes (e.g. a pentatonic scale works really well). Even just using two of the outputs will yield very interesting melodic interplay and is an excellent way to make a simple sequence much more complex and interesting.

In a more basic way the Shifty could be used as a simple Sample/Track and Hold module or as a sequential gate.

Notes: Samara is a "Swiss Army Knife" type of module, intended to serve the most common voltage and audio signal processing purposes such as attenuation, offsetting, mixing, inverting, and even basic waveshaping. Samara features four channels, each with two inputs and an attenuator, additional switchable offset generators, four voltage level and polarity indicators, two adders with switchable scale, and a precision four-channel processor that selects minimum and maximum voltage.
