The clock is voltage controlled with features allowing the module to be used as a sequencer up to 16 stages starting and ending anywhere, any shape of voltage controlled LFO, a multi stage envelope up… Read More

In the great tradition of West Coast synthesis, the Verbos Electronics Touchplate Keyboard is a gold plated controller with 3 independent sections for sending control voltage signals. First is a 32 key volt/oct trimmed piano arrangement with 3 octave selects. It has an output for pitch CV, pressure (actually a measurement of the surface area… Read More

The Sawtooth Stack is a swarm of 5 triangle core discrete oscillators with the  unique waveshaping from the Foundation Oscillator. The pitch Spread of the oscillators can be voltage controlled and they are stretched from left to right through a stereo VCA. The tuning and volt/octave tracking are calibrated when the autotune button is pressed. Notes… Read More

A 5 stage analog sequencer with the ability to transpose the sequence with an external voltage applied to the transpose input. Also, signals can be routed and selected with two 5:1 selectors. Any stage can be jumped to with stage select inputs and front panel buttons or selected with analog voltage. 16HP • +12v 50mA… Read More

In a minuscule amount of space, the Scan & Pan provides a 4 channel mixer with voltage control of level and panning. Since the level control was already there, the “width” and “center” controls from the Harmonic Oscillator are included to allow the user to Scan across the channels, fade between them or actively mix… Read More

The Real World Interface is a 3 channel external processing module intended for connecting with sound sources outside the system. The channels are oriented as vertical channel strips. The left and right channels have a built-in condenser microphone, preamp, envelope follower with variable decay and gate extractor. In addition to a preamp, envelope follower and… Read More

Rooted in the California modular tradition, the Random Sampling is a selection of random voltage sources to add an element of uncertainty to both audio and control paths. Some of them classics and some new twists. Included are 2 fluctuating randoms capable of slowly varying voltage or sweepable audio noise, each with an uncorrelated random… Read More

The Polyphonic Envelope from Verbos Electronics is a unique set of 4 Attack-Hold-Decay envelope generators which can be used together or independently. Cascade logic allows the 4 envelopes to trigger sequentially in 3 modes with subsequent envelopes starting at the Hold, Decay or End of the previous envelope. Each envelope has its own Gate input,… Read More

A simple noise generator and 4 band fixed filter bank. The noise is normalled to the Filterbank input. The cutoff frequencies are matched to the Bark Filter, so that 3 bands of the Bark Filter correspond to 1 band on the Noise & Filter. It is a small and quick noise source and pairs well… Read More

Reimagining the envelope generator, several shapes of 4 stage functions are available simultaneously on each of the two parts in the Multi-Envelope. From the same set of controls and voltage control inputs, each shape has its own dedicated output. All at the same time… Delay Attack Decay Sustain Release, Attack Hold Decay Sustain Release, Delay… Read More

A bank of analog controlled digital delays with 8 taps. When the Delay Time is changed with manual or voltage control, the delay time of all 8 series connected taps sweeps smoothly from 8mS to 150mS each. Included are individual outputs, envelope followers, a manual mix and preset mixes all available simultaneously. The output of… Read More

The Mini Horse is a multi-dimentional touch activated voltage controller. At 42HP wide and ultra thin, it can be added to a synthesizer system either inside the Eurorack or out front in the forthcoming Black Box extra low profile powered enclosure. Twelve keys run across the front, each with its own Gate out, Pressure out… Read More

For the first time in Eurorack, this oscillator module provides outputs for  the first 8 harmonics as sine waves. Also included are triangle, saw, square waves. A voltage controlled mixer with various methods of address allows the user to scan, tilt and mix the harmonics from both panel and external voltage control. It is built… Read More

The long awaited small VCO from Verbos Electronics. It is based on the same discrete transistor core as our other oscillators. In addition to outputs for the Square and Triangle waves directly from the core, there is a brand new multiplying waveshaper giving the effect of a VCO in hard sync with the core. Then,… Read More

Like a time traveler from the tape music studios in San Francisco and New York in the 1960s, this dual filter (based on the core of a classic all discrete transistor filter built way back then), arrives to your studio. The left side is a hipass filter with two cutoff CV inputs, each with a… Read More

The Control Voltage Processor from Verbos Electronics GmbH is a suite of control voltage processing possibilities divided into 3 sections in a slim 18HP package. The lower 2 sections are DC coupled mixers that allow mixing, inverting, offsetting, scaling, multiplying, dividing, crossfading or a combination of these functions. Read More

In the West Coast philosophy of synthesis, one oscillator modulating another is a classic way of creating rich timbres. Voltage control of the modulation and of the waveshape is essential for evolving the sounds from whatever CV sources. Read More

The Bark Filter Processor is a 12 band fixed filter bank with individual outputs and envelope followers on each band as well as a voltage controlled mixer for blending the outputs. The filters are steep, 6th order bandpass filters with yellow LEDs indicating the level at the envelope followers’ outputs. The voltage controlled mixer has… Read More

This is a new version of our old favorite. We have taken the functions of the Amplitude & Tone Controller into a smaller 10HP package and shortened the name to what we have always called it. For those who don’t know, the module is a Sallen-Key lowpass filter followed by a VCA. The signal path… Read More
