Notes: Variable Pole analogue filter based on Asteroid Op VCF Tech

Model: Millipede Variable Pole VCF
Analogue Filter, Can easily get Brutal tones.

What does this do?

This is an analogue filter that uses two modern equivalent ssm2164 IC's v2164 from cool audio to do it's magic. This particular filter however allows the user to vary the phase of each pole or filter cell. There are four filter cells total. This is similar to the Blue lantern Asteroid Operator Station VCF. The Asteroid Operator Station VCF has 8 Static filter out puts. Those 8 flavors were found by exploring the circuit found on the millipede vcf and internally installing the resistor ratio for that flavor.

On the millipede vcf you are allowed to find more exotic flavors yourself. Operation is easy. You first have all the poles counter clockwise and the three switches set to mute. This will have the filter as a dark Low pass filter. Then you turn on a pole using the switch and turn the know to hear the change. Pole 3 by default is always on, otherwise there would have been no sound if all poles were muted. Having all the poles set clockwise and active easily gets you into brutal sounding tones in a good way.

There is an on board diode limiter circuit to help tame really harsh tones. This is activated by switch.

The audio input has some gain, so you don't always have it fully clockwise. There is also a capacitor selector switch just like my other filters. This modifies the rez peak.

Notes: Quantus Ampla is a compact four-channel VCA. But it's not just any VCA: with some unique normalizing, mixing, and CV options, and a bit of NE flair, you can use it for tonnes of stuff. From the top, each channel has two independent modes: Amplify, which gives you normal VCA response, and Attenuate, which makes the VCAs close instead of open in response to positive CV.

The CV inputs are circularly normalled, so you can easily create ducking effects over multiple voices, volume fades, and transitions, all with minimal patching. Plus, the outputs mix down, so it can be two two-channel mixers, a 3-channel mixer plus a VCA, a 4-channel mixer- mix and match to your heart's content. Did we mention it's DC-coupled? Yep, you can use it to process CV signals, too.

You can never have too many VCAs. Your Quantus Ampla is waiting for you.

Notes: Creatively inspiring business from Xaoc as usual. The Erfurt is a digital phase accumulator, digital oscillator, binary counter or clock/audio frequency divider. Versatile stuff.

Supplier's Notes:
Xaoc Devices Erfurt is a digital module that may be used as an 8-output clock and audio frequency divider, a bi-directional binary counter, or a component of the Leibniz binary system, i.e. a programmable digital oscillator.

Erfurt features an 8-bit register which holds its current state: an 8-bit number representing digital values from 0 to 255. The state is available at the front panel via eight binary (5V gate) outputs and reflected by the 8 status LEDs. There are three clock inputs: one incrementing the state at each impulse, one decrementing, and one resetting the state to zero. The state may also be changed manually with two buttons.

When operating alone, the state of Erfurt changes by 1 at each impulse from the clock inputs, so that it counts from 0 to 255 in a cycle (modulo 256). This yields the signal frequency divided by 2, 4, 8, etc. up to 128, available at individual bit outputs. Depending on which clock input is used, the clock patterns correspond to the so called mathematical or musical divisions of the rhythm.

With two different clocks patched to the inputs, the counter alternately increases and decreases its state, and ultimately it counts with a rate proportional to the frequency difference between the clocks. A third clock patched to the Reset input may be used to shorten the sequence thus making the cycle incomplete for even more rhythmic diversity.

When there is a Leibniz data source connected at the back (even as simple as Lipsk), the state increases or decreases in larger steps, depending on the data present at the Leibniz bus (eg. the value programmed by the Lipsk buttons). The counter overflows quicker, and produces more complex patterns.

The state of the counter may be used as a phase input to a digital wave table. Connected to other Leibniz modules, Erfurt may play various roles, eg. it may scan waveshapes in Jena, produce stepped voltages useful for making interesting glissandi with Drezno and any VCO, generate gate patterns animating the spectrum of Odessa harmonic banks, spawn pseudo-chaotic sequences when fed back to Lipsk, etc. Since Erfurt is based on CMOS logic (no CPU!), it can be clocked at very high frequencies (exceeding audio rate), therefore some selection switches are provided for clock pre-scaling.

Notes: A comprehensive solution for stereo signals in Eurorack, the Enhance 2 offers stereo and mid/side processing with tons of CV control. Balance, widen and sculpt frequency bands.

Supplier's Notes:
Moving from mono to stereo sound: a logical progression for any synthesist looking to expand their sonic palette. Making use of two audio channels, rather than just one, quite literally adds another dimension to the capabilities of a synthesiser.

Unfortunately, controlling stereo signals can be a challenge within a modular system. This realisation led to the development of Enhance 2: a convenient yet high-fidelity tool for stereo enhancement. It can be used to adjust balance, width and spectral content, while also opening up a world of mid/side processing; all under voltage control and in just 8 HP.

The primary stereo parameters are balance (moving the sound left or right) and width (making it narrower or wider). The balance circuit uses a true constant-power gain law, while the width stage allows for seamless transitions from pure mono to extra-wide stereo.

In addition, tone control is provided by a pair of unique, wide-ranging mid/side voltage controlled tilt filters with selectable corner frequency. These make 'cleaning up' a muddy-sounding mix straightforward, but also provide unique binaural effects when modulated.

Mid/side processing encodes the stereo signals into one containing only the mono material (mid), and another containing the differences between both channels (side). Apart from the internal tilt filters, mid/side outputs also enable external signal processing such as compression or reverberation. An integrated mid/side decoder returns the results back to standard stereo. And at all times, a LED bar phase meter ensures that phase correlation can be easily maintained.

Stereo field modulation, mid/side equalisation and beyond; Enhance 2 brings true analogue stereo control to the Eurorack world.

Notes: 1U version of the excellent Golden Master, a surprisingly creative little output module which combines radio-style multi-band compression with brickwall limiting and mid-side stereo processing.

Supplier's Notes:
Golden Master is a multiband processor module in Eurorack format. Inspired from the studio mastering and radio loudness units from the 90's, this tool is a game changer for everyone who performs live with a Eurorack synthesizer.

The whole magic of Eurorack lies in its raw sound and simple analog mixes - processing through the Golden Master brings instant punch and sound pressure, as well as controlling the overall volume.

Notes: Transit has two stereo (dual mono) channel lanes of audio with an all-analogue 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 sidechaining 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 each stereo channel lane indicate level via white, blue and pink illumination while engaging mutes illuminates the LEDs with the color red. Master and headphone levels also have their own LEDS for level indication using the same color scheme of illumination.

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.

Notes: Performance-focussed crossfader module designed to simplify the process of morphing CV and audio signals. Quad channel design with lots of creative potential.

Supplier's Notes:
Morphader is a performative tool designed to make multichannel CV/Audio crossfade easy and comfortable. Fading from one quad CV/audio scene to another. The core of the module has four CV controlled crossfaders, each with their individual control and a master fader to control them all. The module mixes the four crossfades at its fourth output, thanks to a clever normalization scheme. Each of them can be easily removed from the mix by plugging a cable at its own output.

Main Features:

CV Controlled four channel crossfader.
Attenuators per input.
Normalized voltages to every input, allowing cv levels morphing.
Fader control to crossfade all channels at the same time.
Cv or Audio switch per channel to change resposne curve.
Leds per channel for signal level monitoring.

Notes: The Five Amp is a throwback to SynthRotek's original 5A Power Supply with some upgrades. It uses a quality 12V power brick for the +12V power regulation instead of a +12V converter. The plus side of doing it this way is that whatever amperage the -12V and +5V rails are not using can be used by the +12V rail, which always draws the most of the three.

Five Amp comes in three different power configurations. It is recommend that you select an option based upon your -12V rail draw. For a rule of thumb, Red (with red LEDs) will power a single row of 84 or 104HP, Green will power two rows of 104HP, and Blue will power three to four rows of 104HP.

Notes: Xer Dualis is a compact analogue four-channel stereo mixer. Each channel has left and right inputs, a level control, and a mute.

Want to use mono signals? No problem! The left inputs normal to the right ones. On the stereo pair output, XD features a simple meter and a clip indicator to keep your mix clean. Xer Dualis is a compact and performable choice whether you need a submixer for a large system or an easy way to mix all the elements of a portable case together.

Notes: ADDAC712 is a dual channel discrete gain staging amplifier, based on a famous discrete preamp board from the 70's used in some legendary equipment.

What was eye-catching was the character of its clipping and resulting saturation/distortion.

The module can be used with modular signals to add a distortion/fuzz character or as a preamp for an external source such as a line source, keyboard, guitar...

It's also a great side companion for our ADDAC711 Balanced Inputs.

At the top an On/Off [BYPASS] switch routes the signal into the Effect (Up: Active) or to the bottom output gain stage (Down: Bypassed).

The amount of amplification is set by the [GAIN] control, the maximum amount of amplification can be set by the user using the [MAX GAIN] trimmer.

Up to +/-5.5v the incoming signal will keep it's integrity, beyond this point saturation will start to increase.

At approx. +/-6v a hard clipping will start to occur, this clipping also has a particular quality that at extreme levels it drifts the audio 0v bias reference, moving it upwards which results are similar to a Gate effect.

In the middle, an x2 opamp based output gain stage with a clipping led, which monitors the clipping at the output, and an [OUTPUT] control to set the output volume.

Having the top and middle gain stages provides flexibility allowing the user to completely distort the signal on the top stage and tame it's output level with the second stage.

At the bottom, Input and Output for both channels (Left input is normalled into Right input).

Notes: ADDAC714 is a dual channel soft clipping module.

Diode based passive clipping acts as a "brick wall" limiter with a fixed knee given by the inherent diode physics. A passive RC low pass circuit adds a 3.3KHz -3db low pass filter which sculpts the overall tone while also adding further character to the effect.

At the top an On/Off [BYPASS] switch routes the signal into the Effect (Up: Active) or to the bottom output gain stage (Down: Bypassed).

The amount of clipping is set by the [GAIN] control, it mostly works as a threshold control for how much clipping will be applied.
As more clipping is applied the signal's amplitude will also decrease, to compensate for this we set up a gain compensation stage to keep the output amplitude balanced across the Gain range.

Symmetry chooses between bipolar clipping or positive clipping, this relates to the harmonics generated, bipolar for odd and even harmonics (up position) and unipolar for odd harmonics only (down position).

At the second stage, an opamp based x2 output gain with a clipping led, which monitors the clipping at the output, and an [Output] control to set the output volume.

Having the top and middle gain stages provides flexibility allowing the user to completely distort the signal on the top stage and tame it's output level with the second stage.

At the bottom, Input jacks for both channels (Left input is normalled into Right input) and output jacks

Notes: Amnis is a shift register with a few tricks up its sleeves. It can be used as a generative sequencer for gates and CV, as a tunable digital noise source, as a random gate and CV generator, as the center of a chaotic system and more.

It needs two input signals to start doing its thing. A Clock and some Data. Data can be pretty much any signals. From these two signals Amnis will generate 8 gate outputs, always on the clock. From these gate outputs, it will generate 3 staircase CVs and a slewed CV. With 8 gates and 4 CV outputs it can be the heart of any patch.

Amnis has an XOR input for linear feedback. A shift register with linear feedback is the core of the Rungler, the chaotic core in Rob Hordijk's Benjolin and Blippoo Box. With Amnis you can recreate these type of behaviors with any oscillators you have on hands.

Amnis is compatible with the Turing Machine expanders thanks to its expansion port at the back.

Due to popular demand for a 3U shift register, Amnis replaces (and expands on) Ruissellement, which was the 1U version of this module.

Notes: Bleeding Hearts Eurorack Modular Device

(Random Sequencer, Rhythm Generator, Destroyer, and Filter)

The Bleeding Hearts is a device that starves, bit crushes, splatters, and filters audio sources like no other. Feeding a gate signal to the Bleeding Hearts enables a whole new world of strange and random analog-generated movement. Each position of the 8-step sequencer can bleed into each other and interact with the destruction effect, creating gated and filtered splatters, glitches, and crunches that move to the beat of your patch.

Designed and assembled in Seattle, Washington. Includes a limited 1-year warranty, if registered within 30 days of purchase.

Notes: Two Of Cups - include samples in your live set. Two of them at once with a wide variety of CV-able features. Simply load one of 8 (!) banks each containing up to 24 samples for each of the two voices and off you go (unlock this feature with firmware 1.1!). Needless to say you can change the samples under CV and if needed - you can set up the trigger delay for each voice because that boy plays its sample so instantly and sample accurate with the with lightning speed. Breathe life and fresh sounds into your setup with a small footprint (6 HP) you would normally need to carry around a gazillion of gear to reproduce the sonic capabilities. Alternatively, use it the boring way and simply play drum one-shots off it.

Notes: 10HP Edges Clone with integrated midi interface and PSImidi which allows any TRS midi cable to be used.

MIDI Functionality:

MIDI Learn: Press this button and send a midi note. The device will use that channel as the base channel

MIDI Mode: This button cycles between two operational modes.

1. 4 single voices trigger on 4 midi channels starting on the base MIDI channel (i.e. base channel is channel 2 so the voices are mapped over channels 2, 3, 4, 5)

2. Simple Poly mode where each voice plays on a different note on the same midi channel

Note about MIDI and Gating: The gate is normalled OPEN by the Gate 1 input. This is by design but will also force the gate open when the device is triggered by midi. Placing a dummy jack will break the open normal the gate will trigger via MIDI normally

Notes: 8HP Tides version 2

Notes: This is 2 x opensource branches. The input of channel one is normalled to all other inputs so you can run this as 1 to 4, 2x 1 to 2, etc. Dual Color LEDs on sliders

Notes: 6HP Micromodule of MI Warps.

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: Popple is an 8hp multimode stereo filter based on the Mutable Instruments Ripples V1 filter section. Popple maintains the buttery smoothness of Ripples filter while giving you two separate audio paths. The audio paths share a resonance, control, a frequency cutoff control, resonance CV input, and a v/oct cutoff CV input. Each channel then has it’s own cutoff CV input with attenuverters (which are normalled to a 2.5V signal).

Popple will also self-oscillate at high resonance settings, when coupled with the v/oct CV control, it can also act as a dual sine wave oscillator.

Notes: Premium analogue delay from Erica's flagship Black Series range. Two bucket brigade device delay lines work simultaneously with smooth crossfading and tons of voltage control. Lovely.

Supplier's 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 design and usability superior. 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 BBD is one of kind analogue delay module. It features two BBD lines: short, 1024 stage and long, 4096 stage, that work simultaneously and you can smoothly fade between those two, thus creating distinct multitap effect.

Furthermore, an advanced BBD clock noise cancellation circuit is implemented that reduces unwanted BBD noise without filtering higher frequencies of audio signal. Most of parameters are voltage controlled, which allows to integrate the module in complex modular setups.

Time

This is delay time manual control.

Because of BBD clock suspension circuit, delay time can be pushed in extremely long regions, however in that case BBD clock noise may appear. The Time CV is added to the knob setting.

In level

This is the input attenuator switch. Select among full amplitude, half amplitude and audio off.

BBD mode

This control smoothly fades between short and long delays. Any setting in-between will result in distinct multitap delay effect.

LFO rate

Adjust the internal modulation LFO rate. The internal LFO controls delay time, and it's automatically disengaged, when an external modulation signal is connected. The LED gives visual feedback on the LFO rate.

LFO shape

Select the LFO shape. Three shapes are available - triangle, square and in-between shape - mix of triangle and square.

Input

This is the audio input of the module. This is manual Dry/Wet mix. The MIX CV is added to the knob setting.

Colour

Even though the module has BBD clock suspension circuit, the colour switch provides extra lowpass filtering of the signal. At top setting no filtering is applied, at lower settings increasing filtering is present.

Feedback

This is the delay feedback manual control. In extreme clockwise settings the module goes into self-oscillation, and by adjusting delay time and BBD mode settings, the module becomes a drone machine. The FBK CV is added to the knob setting.

CV level

This is the Time CV level attenuator. If nothing is patched into TIME CV socket, it controls the internal LFO amplitude.

WET out

This is the WET signal output of the module - use it for advanced patches.

Out

This is the main output of the module.

Time CV; FBK CV; Mix CV;
These are CV inputs for Time, Feedback and Dry/Wet mix.

Notes: Erica Synths Fusion Dual Mixer is designed to mix and overdrive audio signals on the vacuum tube.

Use the Fusion Mixer as two independent 3-input mixers (also for stereo signal mixing) or a 6-input mixer. Special feature of the Fusion Mixer - great tube overdrive effects when level knobs are set to 3 o'clock or above. When used with drum machines, it even emulates sidechain compressors. When used to mix signals from VCOs Fusion Mixer it works as waveshaper, especially, if pulse width modulated pulse signals is used in one of inputs.

All Fusion modules by default are configured to work with regular eurorack PSU.

Due to the fact that cold tube heaters have lower resistance, Fusion modules have significant power consumption peak at startup, when power consumption almost doubles for 1-2 seconds. This is not a problem with linear PSUs that have power inertia, but may cause switching PSU internal protection to turn off power supply. Please make sure your PSU has some headroom before installing multiple Fusion modules.

Notes: The Looping ADSR is an extremely versatile envelope generator. It can act as a traditional ADSR envelope requiring a gate signal to activate or as a looping ADSR. Envelopes can be output with both linear and exponential curves. In Loop Mode it repeats the cycle of Attack, Decay, & Release. Once the Release phase is complete, it loops back to the Attack and begins the cycle again. The Looped envelope can be further manipulated with the Loop Scale knob. Loop Scale shrinks the overall size of the envelope while keeping the ratio of A:D:R identical. All knobs on the Looping ADSR have CV input. As with all Hungry Robot "Modular Boxes" the Looping ADSR can be powered with a simple 9V DC, Negative Center power supply.

KNOBS
-ATTACK: Sets the attack length (1st stage of ADSR cycle). Determines how long it takes to come to full voltage after gate is applied (up to 10 sec.)
-DECAY: Sets the decay length (2nd stage of ADSR cycle). Determines how long it takes to go from full voltage to sustain voltage (up to 10 sec.)
-SUSTAIN: Sets the sustain level. Determines what voltage the envelope returns to after decay stage
-RELEASE: Sets the release length (Final stage of ADSR cycle). Determine how long it takes to return to 0V after gate is released (up to 10 sec.)
-LOOP SCALE: When in loop mode, this knob scales down the length of the envelope while keeping the ratios identical

SWITCHES
-LIN/EXP: Selects the envelope type: linear vs. exponential curve
-LOOP/ADSR: Switches between Loop and ADSR mode. LOOP turns the loop on. ADSR is a traditional ADSR requiring a gate signal
-RPT./GATE: Works only in LOOP mode. RPT. automatically repeats the loop without a gate. GATE mode requires a gate to begin looping.

PATCH POINTS
-LS.CV: CV input for Loop Scale. Allows for CV control of this parameter.
-A.CV: CV input for Attack. Allows for CV control of this parameter.
-D.CV: CV input for Decay. Allows for CV control of this parameter.
-S.CV: CV input for Sustain. Allows for CV control of this parameter.
-R.CV: CV input for Release. Allows for CV control of this parameter.
-GATE: Gate input for ADSR mode as well as Gate/Loop mode
-OUT: Output of final envelope for all modes.

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: The ADDAC302 Nchunk Control module allows you to connect a Nintendo Nunchuck controller to your modular synth, featuring a two-axis thumb joystick, a three-axis accelerometer and two trigger buttons.

The module provides CV outputs for all of the Nunchuck's parameters and special functions to remap the CV outputs. The remapping can be both continuous or step-by-step and can be accessed through either the dedicated CV inputs or the manual controls.

A specially dedicated Mix output averages between the first two CV outputs, a very useful feature for continuous control parameters.

- 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 (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: The window comparator is a very useful circuit building block that is common in general electronics, but rarely found in modular synths. While a regular comparator activates when the input signal voltage is higher than a threshold level, a window comparator checks if the voltage is between two levels (these form the 'window').

Compare 2 combines two such comparators and a logic section in 8 HP. The result is an advanced tool for extracting gates and pulses from analogue signals in Eurorack synths.

The detection windows are defined by the shift and size parameters, which can be varied using the knobs and CV inputs. Complementary gate outputs are available, with big three-colour LEDs showing each comparator's status.

All inputs are normalised from the left section to the right, but the two comparators can also be used completely independently. On the bottom, the outputs from both comparators are combined in various ways by the logic section, which also features LEDs.

You'll find a use for this truly multi-functional module in practically any patch, processing either CV or audio: complex rhythm generator, dual pulse width modulator, frequency multiplier/divider with PWM, digital ‘ring modulator’ with PWM, dynamic depth VCO synchronizer, voltage controlled swing, logic function array with adjustable thresholds... and many more applications waiting to be discovered!

Notes: While modular synthesisers are most often used as stand-alone instruments, they also present exciting opportunities for processing external signals. Anything from an electric guitar to an effects send on a studio mixing desk can benefit from the unique sonic capabilities of even a modest Eurorack system.

However, patching in an external source usually requires an adapter cable and plenty of clean gain to bring the signal to Eurorack level. If the signal source is balanced, a balanced input is required as well to provide the best possible interference rejection.

Receive 2 (or RX2 for short) provides a convenient all-in-one solution. It offers two universal external inputs, which accept both balanced or single-ended signals via XLR or 6.35 mm jack connectors.

The circuit incorporates low-impedance design practices, radio-frequency (RF) filtering and premium balanced receivers to provide transformer-like interconnect performance in a compact and affordable module. And thanks to the electrostatic discharge (ESD) protection, it’s rugged enough to survive the rigours of performing on the road.

The very clean integrated pre-amps feature variable gain, ranging from unity to +40 dB on each channel. As a result, Receive 2 can handle just about any signal source you may encounter, including electric instruments, piezoelectric pickups and many dynamic microphones.

Adjusting the gains is a breeze thanks to the dual peak-responding LED meters. A mix output is included as well, so external signals can be easily mixed directly in the module.

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: The "uMCLK Divider" module can either work as a MIDI clock divider or as an analog clock divider. The divider outputs are assigned differently in both operating modes.

After receiving a MIDI start command, the module works as a MIDI clock divider. There are fixed dividers on 11 outputs. Via the divider output KEYS, triggers can be triggered and mixed via MIDI notes. The keyboard zone extends over three octaves. With the help of the LEARN key, the receive MIDI channel and the lowest note of this 3-octave range can be defined.

When stopped (i.e. after receiving a MIDI stop command or after switching on), the module works as an analog clock divider and divides the analog clock present at the CLOCK input. The 12 analog divider outputs can be reprogrammed via SYSEX. Ready-made SYSEX files are already available (e.g. for even / odd dividers, Fibonacci series, offbeats, etc.). The RESET input resets the analog counters or serves to deactivate the analog divider.

Notes: The module can record the joystick movement up to a length of over a minute. The sequence remains stored in the battery-backed RAM after switching off. When playing the sequence, it can be manipulated in speed and playback direction.

There is a FREEZE function to hold the current joystick position plus an external reset input. In addition, a GATE is set during movement and a CV voltage is output as a function of the joystick movement. The ranges of the X / Y output voltages are bipolar +/- 5v or unipolar from 0 to + 10v. Both channels X and Y have a passive attenuator potentiometer, so that the voltage range can also be set lower.

Notes: The Sampling Modulator is a multi-function module that lies somewhere between a VCO, a Sample & Hold, and an 8 step trigger sequencer.

Sequencer Clocked Sample & Hold

In this mode it acts like a regular Sample and Hold (S&H) but since it is "sequencer clocked", it is capable of much more interesting patterns than the usual S&H melodies.

The CLOCK input can work in two ways: 1. As a typical clock 2. In "positive going hard sync" mode allowing you to create shuffling and polyrythmic effects.

The HOLD input can be used to keep certain notes playing.

Analog Down-Sampling Effect

In this mode (with the clock running at audio rates) you can go from nasty and harsh sampling rate reduction to an almost clean signal. (The clock run up to 25Khz without external CV and up to 200Khz with CV on the input).

Sampling Modulator/Shaper

Thanks to the V/Oct clock, by feeding a simple waveshape such as a sine wave to IN, and pitch CV to the VCO as well as to the Sampling Modulator CV input, their related frequencies and aliasing caused by the sampling rate reduction are capable of creating clangorous metallic sounds, 8 bit textures and much more.

The game becomes much more interesting when you try to destroy the wave by flipping on and off the switches of the sequencer (which at times can make it sound like three VCOs running in unison).

To understand how the Sampling Modulator works, keep in mind that we are working with a temperature compensated ramp core VCO with more than 4 octaves of tracking. This allows the timbre to stay the same while you move through the scale as the internal and external VCOs are synced in a fashion similar to "frequency related sampling rate modulation"

Unusual V/oct VCO You can use the trigger outputs as a pulse VCO. Flipping the switches on and off the switches can offer a lot of interesting timbral changes.

Notes: Module A-112 is the combination of a voltage controlled 8 Bit Sampler and a wavetable oscillator. On top of it the module is able to generate some special effects. A-112 was designed as an additional sound source with the typical sounds of the early 8 bit samplers and is not comparable with the modern polyphonic MIDI samplers available on the market.

Sampling mode: 8 bit audio resolution, 128kB memory in 2 banks 64kB each (equivalent to 2 seconds of sampling time for each bank with 32 kHz sampling rate), audio input with attenuator, overload display in record mode (gate LED), possibility of MIDI Dump to store sounds in a computer via MIDI, non-volatile memory for the 2 samples in the module, manual tune control for adjustment of sampling rate for record and play, CV input (~ 1V/Oct), both manual tune and CV determine the sampling rate respectively the pitch (pitch range is 5 octaves), gate input (not a trigger: the sample starts at the positive edge of the gate signal and is played as long as gate is high or until the end of the sample is reached), manual Gate button, non-filtered audio output (thus quantizing noise can be used as an element of the sound intentionally).

Wavetable mode: special appearance of the sampling mode when playing a sample, the audio input is now used as a second control voltage input for moving through the sample in 256 byte wide loops (wavetables). The control voltage required to move through all wavetables applied to the input "Wave CV In" is in the range -2.5V (wavetable 1) ... 0V (wavetable 127) ... +2.5V (wavetable 256) when control "Atten." is set fully clockwise. To achieve the typical wavetable oscillator sounds the sampling memory must contain corresponding wavetable data (e.g. loaded via MIDI dump). These data contain a set of wavetables with different harmonic content (e.g. a filter sweep) to get the typical wavetable sound while moving through the tables via CV. But you may also use a "normal" sample and go through the sample with CV to obtain partially amazing sounds never heard before. You may use for example sampled speech and go with CV through the syllables or speech shreds to get really very extreme sounds. An ideal addition for this feature is the Offset/Attenuator module A-183-2 which can be used to adjust the position of the wavetable (Offset) and the modulation depth (Att.). The corresponding jumper of the A-183-2 has to be set to bipolar offset (as the A-112 requires -2.5V...+2.5V to pass through all 256 wavetables). As modulation source an LFO (A-145, A-146, A-147, A-143-3), ADSR (A-140, A-141, A-142, A-143-1/2) or a random voltage (A-118, A-149-1) may be used. Even a ribbon controller (A-198 or R2M), the Theremin module A-178, the Joystick A-174 or the Wheels module A-174-2 are useful to drive through the wavetables.

Effects: Additionally, the module offers - in a way free of charge - some effects like delay, reverse delay, pitch shifting or freeze. But it has to be pointed out that due to the 8 bit audio resolution these effects are not comparable to high quality effect units and should be understand as an extra for nothing. The A-112 is not an effects unit!

The sampling time of the A-112 is about 1...30 seconds corresponding to a sampling frequency range of about 60kHz...2kHz (64kB@60kHz ~ 1 s, 64kB@2kHz ~ 30 s).

Technical note: the module uses a battery for the non-volatile storage of the sampling data. Batteries have a limited lifespan and have to be inspected at least every two years. For details please refer to the FAQ page of our website: Lifespan of rechargeable batteries (used for memory backup).
