Notes: Triplatt is a three-channel active/buffered attenuverter and summing mixer. Each channel has a knob, which can function as a unipolar attenuator or a bipolar attenuverter, depending on the setting of its corresponding two-position polarity switch.

Each input is normalled to a built-in precision +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 V or -5 to +5 V depending on the position of the channel polarity switch. Outputs A and B are also capable of a range of 0-10 / -10 to +10 when using the special function switches.

Each output is normalled to mix into the output of the channel below, making it possible to do sub mixes in groups of two or three.

In addition, each channel has a "special function" switch to alter its input voltage in a specific way. Channel A has a 2x voltage multiplier switch, allowing you to double the voltage sent into Channel A. Channel B has a +5V switch, allowing you to add 5V to whatever voltage is sent into Channel B. Channel C has a mute switch, allowing you to completely turn off the signal being sent into Channel C.

Notes: Module A-160-2V is an enhanced version of the standard clock divider A-160. The module is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses.

The Clock input will take any digital signal from, eg., an LFO, MIDI sync, or the gate from a MIDI-CV interface. At the outputs, you have access to three sets of seven different sub-divided clock signals, from half the clock frequency down to 1/128. The low/high levels of the output signals are 0V and about +10V.

The A-160-2V also has a reset input. Whenever a reset signal is sensed, all outputs are set to certain levels which depend upon the selected mode.

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

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

Notes: The mmMidi is a simple & compact MIDI interface for your Eurorack synthesiser. It translates two independent channels of MIDI note, velocity and gate information to corresponding control voltage signals via either a classic MIDI DIN type connection or as a driverless USB MIDI device.

The mmMidi also converts MIDI Clock to analogue x24 fixed clock and run outputs (i.e DIN Sync). The optional mmT expander provides a third MIDI channel of 8 key mapped gate outputs.

Requiring minimal configuration and a pain free set up, the mmMidi makes it easy to sync Pam's clock to your DAW, control multiple synth voices, and trigger drum or sample modules with the optional mmT expander. The new USB-C connection makes it easy to drive your modular not just from your computer but also via your tablet, phone or any USB MIDI Host.

(Note: New 2025 mkII version adds USB-C functionality.)

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

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

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

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

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

Notes: Introducing the BD808, part of our new series of drum modules that brings analog percussion into the modular synth world, instantly turning your system into a self-contained music machine. Its small size, minimalist design, and modern production methods have allowed us to bring the world's most famous bass drum sound generator back at a very low cost. The real thing is here again.

The BD808 is the Roland TR-808's Bass Drum circuit adapted for use in Eurorack format and tuned to sound like a machine that comes fresh off the original 80's assembly line. The adaptation to modular format has allowed us to add some special features like independent Accent levels, a high-powered gain stage, dual-input pulse-shaper, and extended decay - all without compromising the signature sound of the TR-808.

A widely used technique with TR-808 machines is to run the drum sounds through outboard amplifiers to add gain and then pass the sound through just about anything to generate additional harmonics caused by clipping and distortion. In the BD808, we have already included this high-powered output gain stage capable of producing signals up to 20Vpp, extending from the original palette of sounds and allowing you to get an assorted array of harmonized bass drums ranging from sharp attacks to crushed tones using this simple yet effective technique! On the inputs, we have also designed a dual pulse-shaper circuit so you can trigger your BD808 with Trigger/Gate signals from step sequencers, clock dividers, or any other pulse/clock sources. This saves you the need to shape the pulses sent to the module and ensuring the same stable sound at its peak power, regardless of differences in your pulse source.

All these little, but unique, features make integrating this legendary sound generator into your modular easy, unleashing the power of real analog drums and making those speaker cones shake.

Notes: Each of the two sections of the module is capable of performing the analog multiplication of two signals (A and B) and add an offset (C). It can also act as a dual voltage controlled attenuverter, dual ring modulator, dual VCA or four channel mixer (see block diagram below).

The B inputs are routed to an attenuverter that multiplies the signal between -2 to 2, while the offset inputs (C) route through a unity gain attenuverter (multiplies the signal between -1 and 1).

The output of first section is routed to the output of the second (when the first's output is unused), so the second output can act as master to achieve (A1*B1+C1) + (A2*B2+C2) or (A1 + C1) + (A2 + C2) - a 4 channel mixer.

The through-zero (four-quadrant) multipliers in the A*B+C allow for true Ring Modulation. To achieve this, simply connect two waveforms to the A and B inputs.

Notes: Module A-160-2 is an enhanced version of the standard clock divider A-160. The module is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses. The Clock input will take any digital signal from, eg. LFO, MIDI sync, or the gate from a MIDI-CV interface. At the outputs, you have access to three sets of seven different sub-divided clock signals, from half the clock frequency down to 1/128. The low/high levels of the output signals are 0V and about +10V.

The A-160-2 also has a reset input. Whenever a reset signal is sensed, all outputs are set to certain levels which depend upon the selected mode.

These are the most important features of the module:

Three different sets of dividing factors, selected by a three-position switch at the front panel:
- Power of two: 2, 4, 8, 16, 32, 64, 128
- Prime numbers: 2, 3, 5, 7, 11, 13, 17
- Integer: 2, 3, 4, 5, 6, 7, 8

Two output modes, selected by a two-position switch at the front panel:
- Gate mode: outputs act like the outputs of typical binary dividers
- Trigger mode: in this mode the outputs are AND-wired with the clock signal (i.e. the clock pulsewidth affects the pulsewidth of the outputs)
- Clock edge type selected by a jumper on the pc board:
- Positive: the rising edge of the clock signal triggers the state change of the outputs
- Negative: the falling edge of the clock signal triggers the state change of the outputs

Reset behaviour by two jumpers on the pc board:
- Level triggered: the level at the Reset input triggers the Reset
- Edge triggered: the edge of the signal at the Reset input triggers the Reset
- Positive: a high level (> 2.5V) or the rising edge at the Reset input triggers the Reset
- Negative: a low level (< 1 V) or the falling edge at the Reset input triggers the Reset

Output polarity selected by a jumper on the pc board:
- Positive: non-inverted outputs
- Negative: all seven outputs are inverted

Width: 4HP / 20mm
Depth: 35mm (Measured from the rear side of the front panel)
Current: +12V: +50mA, -12V: -0mA

Notes: Noise Random Tools comprises a collection of useful utility blocks that you could use in many of your patches - Clock, Random Pulse, Analog Noise, Sample and Hold, and Slew.

Features:

- Clock and Random pulse source with adjustable rate
- Analog pink and white noise source with very accurate spectrum
- Analog sample / track and hold with very low droop
- Analog slew with adjustable slew rate

Notes: MMF is an analogue, multimode filter with a 12dB per octave slope. Its sonic character swings all the way from classic low pass to squelchy acid lines. Simultaneous outputs of low pass, high pass, and band pass filter types are provided allowing for many variations of the input signal. Whether you're looking for smooth and creamy, or resonant and wild, MMF can go there.

Notes: A-101-6 is a new filter module that uses so-called opto FET's to control the filter frequency. Opto FET's are very similar to Vactrols, but use light dependent field effect transistors (FET's) instead of light dependent resistors (LDR's). An opto FET is a combination of a light-dependent FET and an LED, both put into a small light-proof case. The advantage, compared to vactrols, is a much faster response of opto FET's compared to LDR's - this allows much faster attack/decay times and even FM effects.

The variable resistors corresponds to the opto FET. The brightness of the Opto FET LED's, and consequently the filter frequency, can be adjusted manually (Frequ. control) and controlled by means of an external control voltage (CV) with attenuator. The LED at the front panel reflects the LED brightness inside the opto FET's.

The type of filter is chosen by jumpers on the PC board (factory setting: low pass). The type of filter determined by the jumpers positions can be marked by means of a water-resistant felt pen at the front panel.

The resonance is controlled by the Feedback control up to self-oscillation. By means of a trimming potentiometer the maximal feedback can be adjusted. High feedback values can be used mainly in the all-pass mode to obtain very extreme self-oscillation sounds. Even an external feedback signal can be used instead of the internal feedback connection (FB In socket). Whenever the filter type is changed by means of the jumpers the trimming potentiometer for the maximal feedback has to be re-adjusted.

The Mix control is used to pan between the original signal (CCW position) and the effect signal (CW position). In filter mode (LP/HP) this control is usually set fully CW. In the all-pass modes one obtains phasing sounds at centre position or "pure" all-pass sound in fully CW position.

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

Notes: Div is a 2 channel, voltage controlled clock divider and multiplier. Incoming clock signals can be multiplied or divided by a factor of 16 with a multitude of values in between.

CV inputs provide external control of the current clock rate, allowing for the creation of dynamic rhythms from a single clock signal.

Notes: Module A-160-5 is a voltage controlled clock multiplier. The incoming clock signal (socket Clock In) is multiplied by a factor that depends upon the control voltage on socket CV In (0...+5V) and the position of the Mode switch. The multiplied clock signal is available at the socket Clock Out. According to the position of the Mode switch different clock multiplying factors are assigned to the control voltage. With 0V CV no clock output is generated. This state is indicated by "all LEDs off". With increasing CV integer factors (left position of the mode switch), power of two factors (middle position) or a mix of both (right position) are obtained. Nine LEDs are used to show the currently selected multiplying factor. In addition two LEDs are used to display the incoming and outgoing clock signal.

A manual control is used to adjust the clock multiplication factor manually without the need of an external control voltage. The voltage generated by this control ("Manual") is normalled to the CV In socket. As long as no plug is inserted into the CV In socket the clock multiplication factor is adjusted by means of the manual control knob and displayed by the LEDs. For dynamic applications (like the ratcheting function described below) the manually generated CV is overwritten by the external CV which has to be fed into the CV In socket.

The module can be used for all kind of clock multiplying applications. One important example is the generation of so-called ratcheting sequences. The band Tangerine Dream is famous for this kind of sequences. A normal sequencer generates only one gate signal per step. A ratcheting sequence may have also more than one gate pulses per step. This function can be obtained by using the A-160-5: one CV output of the sequencer is used to define the number of gate pulses per step. If the control of the step in question is fully CCW the generated CV is 0V and no gate signal is generated (mute of the step). When the control of the step in question is turned clockwise one, two or more gate pulses are generated depending upon the position of the mode switch and the voltage generated by the CV at this step.

Technical note: Due to the nature of clock multiplying it takes a few input clock pulses until the clock output is stable. One has to average a few input clock pulses to generate the multiplied clock output signal. Even when the input clock frequency changes it will take a few cycles until the output clock signal is correct as the module cannot foresee the future of the clock input signal. The generated clock output signal is derived from the last few cycles of the clock input signal. Consequently the module should be driven only by a clock signal with constant or slowly changing frequency.

Notes: The Voltage Controlled Amplifier or "VCA" is one of the most essential and useful building blocks in a synthesis patch. The DUAL VCA 1U packs two high quality, DC coupled, linear VCAs into a very compact 1U package.

The two VCAs can be used completely independently or in tandem via the handy signal normalling. The DC coupling means that the VCA can be used for the amplitude control of both control voltages (CV) and audio signals.

Some application/use examples:

- Dual, independent VCA for dynamic level control of two different audio or cv sources
- Stereo VCA (use the CV normalling where CV A normals to CV B) for processing stereo sources or CV pairs.
- CV/Audio summing (when Out A is not patched, it normals to sum with OUT B, CV A and B control the independent levels)
- Voltage/signal doubling (use input A only and the doubled voltage will appear at OUT B when a CV of +5V applied to CV A)

Notes: Inamp is a dual pre-amp in just 4 HPs. Featuring 6,3 Jacks inputs as well as Minijacks.

Both inputs are summed so you can use them at the same time as an input mixer.

The unit is designed to amplify up to x20 the input signal, allowing to amplify most of the music machines out there (Domestic line levels) as well as some guitars (Humbucker-like pickups and so).

The first channel is normalled to second one in series, so it's possible to have two stages of amplification or two separate ones.

Notes: The Row Power 25 is a clean, regulated, and protected power supply module for Eurorack systems. It requires a barrel-style power brick (15V - 20V DC) and supplies power to modules via flying bus cables, direct connection, and/or bus boards.

The Row Power 25 provides 25W of power for any Eurorack modules (typically 4-10 modules*):

+12V @ 1.4A maximum, 1.0A recommended
-12V @ 0.8A maximum, 0.5A recommended
+5V @ 1.0A maximum, 0.8A recommended

*number of modules can vary depending on each module's power consumption.

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.

Multiple Row Power modules can be powered from a single power brick by daisy-chaining with an inexpensive barrel cable. The Row Power 25 can also be daisy-chained to Pods. Each Row Power and Pod will be independently regulated and protected for ultra-low cross-talk between rows.

Notes: A-135-2 is a miniature version of the A-135-1. Behind a front panel with 8 HP only four linear VCAs (voltage controlled amplifiers) and a voltage controlled mixer based on the VCAs are available.

Controls, In/Outputs and Functions of each VCA:

- Level (manual control of the VCA amplification), small rubberized knob (L1...L4)
- Control voltage input with associated attenuator (CV1...CV4), for the full VCA control range about 0...+5V control voltage are required (attenuator fully clockwise), for higher control voltages the attenuator is used, the attenuators are without knobs, just plastic shafts with white marker
- Signal Input
- Signal Output
- All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages (e.g. to control the level of LFOs or envelopes)
- The signal input is not equipped with an attenuator. But the VCAs can process all signals up to 15Vpp / -7.5...+7.5V without clipping. In case of higher levels an external attenuator is required (e.g. A-183-1).
- The available amplification range is 0...1, the maximal amplification is 1 (i.e. it "clips" and remains at 1 even if the control voltage goes beyond the value that corresponds to amplification 1)

Functions of the voltage controlled mixers:

- Two outputs ("Selected" and "All")
- Selected output: the ouput if a VCA is removed from this sum signal when a plug is inserted into the corresponding VCA output.
- All output: sum of all VCA outputs, regardless of inserted plugs into the VCA outputs
- The maximal amplification is about 0.6 to avoid clipping at the mixer outputs (otherwise the outputs may distort with 15Vpp signals at each signal input and full amplifications)

Special functions of the voltage controlled mixers (selectable by internal jumpers):

- Dual Stereo VCA: In this case the control unit of VCA1 (L1 + CV1) affects also VCA3 and the control unit of VCA2 (L2 + CV2) affects also VCA4, the control units of VCA2 and VCA4 are out of operation
- Quad VCA: In this case the control unit of VCA1 (L1 + CV1) affects all four VCAs. The control units of VCA2, VCA3 and VCA4 are out of operation. In this mode the module has the same function as module A-132-2. That's why module A-132-2 will be discontinued.
- Normalling of the signal inputs: by means of internal jumpers signal input 1 can be normalled to signal input 2, signal input 2 to signal input 3 and signal input 3 to signal input In 4. That way the same input signal can be distributed to four different channels by means of control voltages (e.g. quadrophonic distribution of audio signals). Suitable control voltage sources are e.g. A-144 (Morphing Controller) or A-143-9 (Quadrature LFO).

Notes: Stmix is a compact 4 channel stereo mixer with an Auxilliar input. This input will allow us to chain a few of them or to insert an extra fifth input.

This module is compatible with Befaco's Hexmix system, and can be internally connected to hexmix module to add the output of STMIX to your main mix.

Notes: The Listen IO is a simple module which gets signals in and out of a Eurorack system by converting to and from normal modular levels. The top section converts any external signal to modular levels by providing up to 30x gain (+30dB), allowing you to use table-top synthesizers, keyboards, phones/tablets, computers, toys, microphones, etc. in your patches. The bottom section does the opposite: modular signals are converted to normal line level signals. The bottom two jacks can be used as line outs or as headphone jacks, so you and a friend can listen in stereo at the same time.

Each section has two inputs and outputs for use with a stereo signal or two mono signals. An LED bar graph for each output shows the signal level and clipping.

Notes: Terci Ruina combines three classic distortions in 4 hp. Distortions are reinterpreted in classic NE style and routed through each other for complete sonic annihilation of any sound. Patch in and out anywhere in the signal chain to pick the best sound for your purpose (because modular). Looking for a pretty distortion? This is probably not your module. Unapologetically gross and dirty.

Notes: The 333 is a summing and distribution module for Eurorack modular systems.

It is composed of three identical sections, the red, yellow and green, each of those featuring three inputs summing amplifier with three independently buffered outputs.

Derived directly from the CGM creative mixer series, the sum section is DC coupled, allowing the sum of control voltages as well as audio signals.

With an extremely low tolerance in both sum and output sections, it is suitable also for summing quantized voltages like the ones coming out from the quantized outputs of the SAPEL.

In case CVs or audio signals are particularly hot, the 6dB attenuator might be helpful to reduce exactly by 50% the incoming signals.

Red and yellow output are also normalled to the 1st jack socket of the yellow and green input: in this way this module can also work as a 1 to 9 buffered multiple.

Notes: This module connects via 3 pin cable to the Intellijel Pedal I/O 1U module.

It provides the 1/4" TS interface for connecting guitar pedals or instruments.

Notes: Sinc Pravus is the Goldilocks of a quad offset in 4HP. Whether your CV ranges are too high or too low, Sinc Pravus is just right.

Use the back-panel switch to configure Sinc Pravus to either ±5 or ±10 volts. To use Sinc Pravus as a DC-voltage generator, just leave the input unpatched.

Each of Sinc Pravus's four channels are controlled by a dedicated potentiometer with an LED for monitoring signal outputs. The input jacks are normalled from top to bottom so it can offset the same signal by different amounts or simply act as a mult.

Sinc Pravus is a workhorse in 4 HP.

Notes: Designed with versatility in mind, MapVolt is a dual-channel Universal Voltage Processor built for flexibility in handling audio and CV signals.

With only 6hp, Mapvolt is a multipurpose tool for voltage-controlled scaling, inverting, offsetting, subtracting, and mixing functions.

Each channel of MapVolt can operate in either Polarizer or Attenuator mode, allowing manual control via knobs or CV signals. In Polarizer mode, it functions as a Voltage Controlled Attenuator-Inverter, granting control over signal level and polarity. Additionally, it can be used as a Four-Quadrant Multiplier or Ring Modulator for audio signals, with the processor input serving as the carrier signal and the polarizer's CV input acting as the modulator.

In Attenuator mode, MapVolt operates as a VCA, providing control over signal levels. Its VCA CV input range of +5/-5 makes it well-suited for amplitude modulation (AM) with other +/-5V waveforms.

MapVolt is equipped with dedicated Voltage Offset knobs for each channel, which can be controlled via CV. If no input is patched into the Processor input channel, the Voltage Offset knobs can be used as Offset Generators.

With its dedicated mixing stage, MapVolt enables the combination of both channels into a shared output. Furthermore, if one of the processor channels is inverted, it allows for the subtraction of one signal from the other.

Notes: Module A-101-8 is a 8-stage phase shifter which uses light-sensitive resistors (LDR) and is a replica of the Compact Phasing A manufactured by the company Schulte in the seventies. The actual phasing circuit is identical to the historic model. Only the illumination control of the LDRs is different: the A-101-8 uses LEDs to illuminate the LDRs, the historic model used incandescent miniature lamps. And the A-101-8 has no built-in LFO but can be controlled by any external control voltage source (e.g. LFO, ADSR, random, Theremin, ribbon controller, sequencer, midi). The phasing offset (i.e. the base value for the phase shifting) and the modulation depth of the external control signal can be adjusted separately. The Compact Phasing A had no offset control but only a depth control for the built-in LFO. Feedback and mixing ratio of the output signal are set by two controls. The audio input is equipped with an attenuator. The module has two audio outputs available (same as the historic model) and a visual display of the phase shifting.

The module has these controls and in/outputs available:

Control Man. : manual control of the phase shift offset (base value)

Control CV: attenuator for the signal applied to the CV socket

Control Feedb.: Feedback or Resonance (similar function as filter resonance/feedback/emphasis)

Control Mix: sets the mixing ratio between original and phase shift signal appearing at output 1

fully CCW: only the modified input signal appears at output 1 (see note below *)

center: a mixture between the modified input signal and the phase shift signal appears at output 1, that's the standard position for the classical phasing effect

fully CW: the pure phase shifted signal appears at output 1 (e.g. for vibrato effects)

Control Input Level: attenuator for signal applied to the In socket

Socket In: audio input

Socket CV: control voltage input

Socket Out 1: audio output 1 (mix signal)

Socket Out 2: audio output 2 (modified input signal)

LED: visual control of the phase shift

The module has some peculiarities (same as the historic model):

The input signal is processed at first by a pre-stage which outputs a "modified" input signal (*). This signal is not processed by the phase shift stages but is affected by the feedback setting. Only when feedback is set to zero this signal is identical to the input signal. Otherwise it contains feedback components.

This signal is output on socket Out 2.

When both output sockets Out 1 and Out 2 are used as stereo channels one obtains a spatial stereo sound effect.

The same signals is also used for the CCW position of the mix control. With mix control fully CCW the unmodified signal appears only if the feedback control is set to zero. Otherwise it contains feedback components.

The historic model had two audio inputs: one 5-pin DIN socket and a 1/4" jack socket. The DIN socket was intended for high-level line signals. When the 1/4" jack socket was used the amplification of the pre-stage increased by about 100. The 1/4" jack socket was intended for low level signals (e.g. electric guitars or microphones). For this feature the A-101-8 has an internal jumper that can be used to increase the amplification. As long as the module is used within the A-100 system usually the lower amplification is used to avoid distortion.

The 8 photo resistors and LEDs are assembled within an small lighproof box. In addition the pc boards are made of lighproof black material to avoid interfering light from other modules or the bus board.

Notes: Module A-171-4 is a fourfold voltage controlled slew limiter. It's intended purpose is polyphonic portamento but can be used also for other applications where several slew limiters are required.
The common slew time can be adjusted manually and in addition controlled by an external control voltage. The module uses light-sensitive resistors (LDR). Therefore the slew times are not exactly the same for all units due to the tolerances of the LDRs and the LEDs, which are used to illuminate the LDRs. Inputs and outputs of the slew limiters are buffered to avoid voltage drops. This is especially important for polyphonic portamento applications. Each output can drive several VCOs without the need of external buffers. In addition the slew limiter inputs and outputs are available at internal pin headers for internal pre-wiring of polyphonic patches. 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:
Control Man. : manual control of the slew limiter value (base value)

Control CV: attenuator for the signal applied to the CV socket

Socket CV: control voltage input

Sockets In 1...4: slew limiter inputs

Sockets Out 1...4: slew limiter outputs

LED: visual control of the slew limiter value (dark = long time, bright = short time)

Technical notes:

Each light-sensitive resistor (LDR) forms together with an associated capacitor a simple standard RC network (Resistor/Capacitor network). Input and output of each network are buffered.

The slew time range is about 5 ms ... 10 s (1:2000). Due to the tolerances of the LDRs and the LEDs the slew times vary a bit for each unit. By changing the capacitor values this range can be altered: by lowering the capacitor values the slew limiters can be used as 6dB low pass filters. Increasing the capacitor values result in longer slew times

The 4 photo resistors and LEDs are assembled within an small lighproof box. In addition the pc boards are made of lighproof black material to avoid interfering light from other modules or the bus board.

On the module pc boards two pin headers with 4 pins each are available. These are planned for the internal pre-patching of polyphonic modules:

In 1...4: The pins of this pin header are connected to the switching contacts of the sockets In 1...4. Hereby an internal four-wire connection to the CV outputs of the polyphonic midi-CV-interface A-190-5 can be made. As long as the sockets In 1...4 are not used the internal connection to the A-190-5 is established.

Out 1...4: The pins of this pin header are connected to the outputs Out 1...4. Hereby an internal four-wire connection to the CV inputs of the polyphonic VCO A-111-4 can be realized. If more than one VCO has to be controlled by one output we offer so-called micro multiples.

Notes: Add external feedback loops, tilt filters and more to the Timiszoara effects module with this versatile expander. A must-have for Timiszoara owners.

Supplier's Notes:
Deva is an expander for Xaoc Devices' Timiszoara multi-fx module designed for creative exploration of the dirty/nasty side of signal processing. Deva opens up the Timiszoara programs you've come to love with some unexpected twists and turns along the way. The analog side features two external feedback loops (for the left and right channel) with tilt filters adjustable via sliders with two additional switches for choosing positive or negative feedback (for each channel). The third slider controls the DAC clock - from overclocking by a factor of two down to 16-times slower, so you can go from chipmunk to hardcore teeth gnashing of underclocked goodness. A switch allows for turning the clock control off for normal/regular operation. All features have inputs for external CV.

Notes: ADDAC809 is a dynamic CV operated I/O router that allows one source (Audio or CV) to be routed through 2 different chains (of one or more modules) before being sent to an output.
Six routing patterns are allowed:

1. IN > OUT
2. IN > CHAIN A > OUT
3. IN > CHAIN B > OUT
4. IN > CHAIN A > CHAIN B > OUT
5. IN > CHAIN B > CHAIN A > OUT
6. IN > > OUT
A practical example is to have an audio source, a delay and a looper.
And the question: should the delay be placed before or after the looper? Sometimes you may need the delay to be before the looper as you may want to sample the audio with the delay or sample the pure audio source and apply the delay afterwards.
This small utility module solves this issue on the fly without having to repatch anything.

INPUTS & OUTPUTS

TO CHAIN B: Connect to your Chain B input
FROM CHAIN B: Connect to your Chain B output
TO CHAIN A: Connect to your Chain A input
FROM CHAIN A: Connect to your Chain A output
INPUT: Connect to your Input Source
OUTPUT: Connect to your Output Source

ROUTING PATTERNS

There are 2 ways to address the six routing patterns:

Buttons: using the frontpanel push buttons and/or dedicated trigger inputs to latch between 2 states.
BYPASS: Chooses between Pattern 1 and any other pattern
PARALLEL: Chooses between Pattern 6 and any other pattern
ORDER: Chooses the order A before B or B before A
DUAL/SINGLE: Chooses to use a Dual (A>B or B>A) or Single chain (A or B)
CV: The dedicated CV input expects a 0 to +5v input and allows to jump to the precise routing pattern using a specific voltage interval in increments of approx. 0.83V:

Pattern 1: 0v to 0.83v
Pattern 2: 0.83v to 1.66v
Pattern 3: 1.66v to 2.5v
Pattern 4: 2.5v to 3.33V
Pattern 5: 3.33v to 4.16V
Pattern 6: 4.16v to 5V

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

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

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

This module can be used as:

two independent crossfades

two independent VCAs

stereo crossfade or Dry/Wet control

stereo VCA

panner

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

Output 1 is mixed with output 2 if left unconnected.

Notes: FONT is a massive sounding liquid filter- designed to bring you powerful basslines, tons of FM modulation and a clean resonance over your audio path.

It features two simultaneous outputs:
2-pole Low Pass
2-pole Band Pass

It can also work as a sine oscillator, tracking 1V/OCT when the resonance is at its maximum level.

FONT can be used to make basslines, acid patterns thanks to its organic and musically sounding resonance.

Ping it to produce percussion sounds such as, bongos, congas or toms.

Applying a pitch envelope, it really shines as a kick-drum machine!

Notes: This is a 4 mono channels expansion. Several of these modules can be added to provide more channels. Every channel features:
- Mono input
- Vactrol Gate (plug a CV into the GATE IN to modulate the volume of a channel, just like a classic VCA. When nothing is plugged in the GATE IN, the gate is normalled to fully open)
-SEND A control (switchable PRE/POST, in PRE mode the signal is present regardless to the channel volume control but only if the channel switch is in ON position)
-SEND B control (post-fader)
-PAN control (only affects the master bus)
-VOLUME control (affects the master, cue and POST sends, does not affect PRE-fader send)
-ON/OFF/CUE switch: ON - channel is routed to the master bus
OFF - channel is muted
CUE - channel is routed to the cue bus

Notes: Mutes goes above and beyond basic muting by allowing you to split groups of signals to multiple destinations, making it great for FX dub performing and varied signal routing.

You also get a three position switch giving you: MOMENTARY signal pass through (it springs back to the centre when released); OFF (or muted) in the centre; and ON to the right. We've also added vactrols to the circuit giving the switching a pleasing decay for both audio and modulation as well a totally click free muting. This module can add mutes to anything, your mixer, module inputs or outputs, modulation signals, sequencers, gate sources and more.

Mutes was developed by Befaco on behalf of DivKid.

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

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

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

Notes: 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: This new module should not be judged by it's size, at 6hp it's packed with features.

At its core it features a noise source and two precision Sample & Holds with 0.01% of maximum deviation from the Input which allows for quantized signals to be sent through without any noticeable detuning or the typical voltage drops over time.

The Sample & Hold sections can also be used as a Track & Hold meaning it holds the incoming input while the Trigger input is ON and lets the input flow to the output when the Trigger input is OFF.
Each section also features it's own slew processor with a single control over attack and decay and an ON/OFF switch.

The noise signal is normalled to both sections inputs, meaning that without a jack plugged into the Input the sample and hold function will act upon the incoming noise signal generating random CV values.

The [Trigger A Alternate] switch allows to Link both sections so that any trigger input in Trigger A will alternate between triggering the A and B section.

Besides each section outputs there's also 4 extra outputs: Noise, Difference, Average and Sum. The Noise output is coming from the noise source, the Difference output is the subtraction of section A minus section B, the Average output is the sum of both A plus B and then divided by 2 and finally the Sum output is the sum of both A plus B sections.
