- "Trig. In" to trigger Pulser
- "Pulser" controls rate of pulses fired between .002 and 10 sec and the amount of pulses can be manually controlled or via CV "Time" input
- Length (PW) of pulses can be manually adjusted from 0 - 100% and can be CV controlled via "Length"
- Outputs pulses and sawtooth
- Manual buttons for "Start" and "Stop" and both can also be CV controlled
CV and Pulse Outputs:
- 4 rows (A-D) of 5 step voltage generators with individual CV or Pulse outputs + LED indicators
- "All Pulse" output
- 5 "Stage Select" switches with trigger inputs and buttons for stage selection. Switches control length of sequence.
- Stage Select "Address" CV input for controlling additional stage selection
A very buchla-esque five-step analog sequencer with step selection and addressing, individual pulse outputs and four CV rows. Manual buttons for selecting stages are great for direct, haptic play with the module - even without a clock e.g. for recalling presets. Its clock generator is pretty flexible, voltage controllable and offers variable gate length, buttons and inputs for transport functions. Plus it has a wide range, from LFO to audio.
The module can be split in two halves:
1) Sequential CV and pulse source alias an analog sequencer.
2) Controllable clock generator / transport section / control central named Pulser.
- 6 total inputs with mute switches and volume control on each channel
- Panning knobs for channels 2-4
- Channels 1 and 6 allow for panning via CV input; the 1st channel is panned left and the 6th channel is panned right by default and +5v input will change pan (LEDs will signal left or right)
- Stereo output, direct pre-fader mono sum output and attenuated headphone output
Six-channel mixer module with panning (even with voltage control on two channels), mute function, a headphone out and main outputs with VU meters. Intended to be used as a final mixer in your system. Version 2 is a revision of the original analog circuitry to get rid of the annoying bleed-through. Each channel has a level control and a mute switch. While channels 2 to 5 offer manual panning, channels 1 and 6 are different: channel 1 is panned left and channel 6 is panned right in their default states, both panorama positions can be voltage controlled, though. There's a pre-fader mono output that ignores panorama positions and level controls. The 3.5mm headphone output is stereo and features an attenuator. The stereo mix is available at the L+R sockets and its level is visualized with two LED chain VU meters.
- Processes incoming CV via a front a panel attenuator for bi-directional voltage control.
- Inputs 2 and 3 can be crossfaded by CV (0 to +5V) or manually using the crossfader knob.
- DC offset can be added to the final sum of the input stage.
- Sum output of In 1 and the crossfaded mix of In 2 and In 3.
- Two independent amplifiers with manual control of gain ranging from unity to 2x gain. Designed to amplify Sputnik-standard 0-5V control voltages to up to 0-10V ranges for use with other Eurorack modules.
The CV professor attenuates, crossfades and sums signals. And on two independent channels he can amplify signals up to the factor 2.
In the upper part we find three signal inputs: the first has an attenuator, between the second and the third can be cross-faded, which you can handle with the potentimeter and with a CV. Centrally placed in the output section there is an offset control, generating a voltage from 0V to +5V. The three input signals are summed with the offset voltage and are output at the SUM socket.
At the bottom two individual amplifiers are located and their controls allow you to set the amplification factor between 1 and 2.
- Eurorack modular level audio input (10V p2p). If no input is present, the output of the preamp section is normalized to the envelop follower input.
- Outputs a 5V pulse when the CV level (after the Sensitivity attenuator) exceeds approximately 2.5V. Pulses may trigger envelopes, sequencers, or pluck a low pass gate.
- Outputs a CV value (between 0 to +10V) based on the amplitude of the audio input. Allows audio to control any number of CV parameters on Eurorack format modules.
- Acts as an attenuator for the incoming audio signal, allowing hotter signals to be brought down below the pulse output threshold. Simultaneously acts as a range control for the envelope follower's CV output.
- Controls the decay of the CV output. A lower setting allows for a quick CV response that matches the audio input while a higher setting allows for more of a slew between amplitude peaks.
- This switch selects between two pulse response modes. Transient mode produces short pulses based on the CV output rises above approximately 2.5V. Sustained mode produces sustained pulses that are held at 5V when the CV output is higher than a ~2.5V threshold.
- Controls the amplification of the input signal. At fully closed the incoming signal will be completely silent and at fully open the maximum amount of gain will be applied.
- 1/4" TRS balanced instrument input jack.
- Three gain modes (low, medium, high) are selectable based on how much amplification your audio input requires. Gain is applied after the Gain Attenuator.
- Two position switch for Mic mode for balanced signals (such as microphones) or Instrument mode for unbalanced signals (guitar, bass, or line-level audio such as keyboards or drum machines).
- Amplified audio output

The Multi-Touch Keyboard Controller is a touch keyboard which exceeds the capabilities of other units available so far. It has 29 semitone quantized touchpads in a classic keyboard layout with an octave switch and pressure sensor plus a separate ribbon controller. It can be used in a monophonic or in a maximum four-voice polyphonic mode and even features an arpeggiator. Latter has an internal tempo generator but of course can be synchronized to an external clock.
The touch plate keyboard has 29 keys and interprets the finger pressure by measuring how much skin has contact with the plates.
Attack and decay:
- 4 generators
- The time range of each generator (.005 - 10 seconds) can be controlled via CV pulse input jacks for both attack and decay + control knobs
- 3-mode switch per generator: CYCLE (LFO), TRANSIENT, SUSTAINED
- Each generator includes CV output + pulse output that generates a transient pulse at the end of the decay segment: if the generator is in CYCLE mode for instance, that cycle will repeat
- QUADRATURE MODE SWITCH with green LED: when engaged, 1+2 (or 3+4) work in tandem + a shift of 90 degrees to each other. These pairs can then be linked creating complex ADSR envelopes.
- Dedicated outputs for 1+2 and 3+4 as well as attenuator knobs for mixing channels.
This module contains four voltage controlled function generators that can be used in pairs, in order to mix them and additionally to create more complex envelopes in quadrature mode. Each channel can be used as an AD envelope or as LFO and also generates pulses.
Each channel of the QFTS is an individual function generator that, when having received a pulse at it's input, will generate an attack-decay cycle. The attack and decay times go from 0.005-10 seconds and each can be voltage controlled. When the AD-cycle is finished, a pulse will be generated at the pulse output. In cycle mode this output can be used as square wave LFO with a pulse width depending on the relationship of attack and decay times.
- Four inputs accept CV or audio signals with stage selection LED indicators.
- Three mode switch allowing for selection between 2, 3, or 4 inputs.
- Selection can be advanced by trigger, gate, or clock signals via an input jack or using the dedicated trigger button for manual selection at slower speeds.
- Trigger input, gate input, or manual momentary button control of sequence reset. Reset defaults Selector back to Input A.
- Signal output.
Choose between 3 sequential modes at a time: UP (DCBA pattern), DOWN (ABCD pattern), or RAND (random pattern mode). PENDULUM mode (ABCDCBA pattern) is also available as a hidden feature when pressing and holding the "TRIG" and "RESET" buttons simultaneously for 3 seconds. This will swap UP with PENDULUM mode and is reversible by repeating the same process.
In a different way than other Sequential Switches the Selector not only switches forwards thru the inputs but also backwards or in a random fashion. Then it has an inverted output and a step count limiter, but it does not work bi-directionally. Read: It is a "4 In / 1 Out" switch and it's not possible to use swap inputs and outputs.
