Synth modules

Notes: 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. The top section is a voltage controlled slewing processor with independent control of Positive and Negative slew rate, with some unique tricks. The Positive and Negative slew, or Rise and Fall rates if you like, have reversing attenuators. The slopes can be blended from linear to RC curves (starting all slides fast and ending slow, like a proper "East Coast" Portamento) without a change in speed. It can be triggered like an AD envelope and has a Gate out that goes high when the CV out is below 100mV. Of course it can loop by patching the Gate out to the Trigger in. The Bounce control adds a unique flare of overshoot to CV changes, a bit like the effect of stopping a tape reel from turning and then letting it go. The combination of multiple voltage processors offers the user the functions of analogue computer.

Notes: Inspirational west coast sounds from one of the masters. Additive oscillator with eight harmonics, direct outputs and powerful CV control to scan, tilt and mix the waveforms.

Supplier's Notes:
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 on a discrete, all analog triangle core with an old school discrete transistor exponential converter. It has inputs for linear and exponential FM, the exponential with a reversing attenuator. Of course there's a 1 volt/octave trimmed CV input as well.

Power consumption: 120mA at +12 V and 90mA at -12 V

Notes: The Multi-Delay Processor is a creatively usable echo effect with eight taps. The module's sound may remind you of classic bucket-brigade devices. - It even generates distinctive pitch effects when altering the delay time. An input mixer gives audio material a crisp, analogue character. Thanks to feedback channels with pitch shifter and reverb processor, shimmering echoes and other atmospheric effects can be achieved. A total of nine envelope followers and 14 audio outputs invite you to do extensive feedback patches and other edgy experiments.

The Multi-Delay Processor isn't just a high-quality echo effect but was designed to be a fundamental ingredient of patches. Its core is a bank of eight digital delays, which are wired in series. Together, the circuits form a multi-tap echo. The volume of each signal repetition as well as the raw material can be adjusted via faders. Furthermore, there are individual audio and envelope follower CV outputs for the dry signal and all taps. An analogue clock is used to control the echo circuits. The delay time can be set manually via a potentiometer plus there are two CV inputs with bipolar attenuators. Altering the delay time parameter during operation leads to pitch effects. At this point at latest, you'll realize the superiority of the serial memory design used by Mark Verbos over average effect chips. Despite its digital core, the Multi-Delay Processor offers charming sound reminiscent of a classic bucket-brigade device. - Only cleaner and more transparent.

A three-channel mixer with dedicated level potentiometers adds analogue character to signals before they are fed to the delay circuits. Without patch cables plucked into the second and / or third input, you can use these channels as feedback paths with additional effects. In detail, a pitch shifter calibrated to +1 octave (channel 2) and a reverb (channel 3) are available. - A perfect setup for creating shimmering echoes and other atmospheric effects. High feedback values make the module self-oscillate. In contrast to the multi-tap delay, which consists of individual components, an FV-1 chip is used for pitch shifting and reverberation. This processor is well-known, as it is the main component of multi-effects modules like the Erica Black Hole DSP and numerous guitar pedals. Here, the FV-1 is "just" a creative addition to the main effect.

In addition to the manual mix output, which emits the mixture of raw and effect material dialled in via the faders, there are four other audio outs. Two of these connectors provide signals derived from summing up all even respectively odd taps. The other sockets emit preset mixes with increasing or decreasing level. - Very cool for quickly creating special effects.

Notes: 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 four bands of the Bark Filter correspond to a band on the Noise & Filter.

It is a small and quick noise source and pairs well with Scan & Pan and Amp & Tone.

Notes: Explore modulation beyond the standard ADSR with Verbos's complex polyphonic envelope, opening up the potential of ADAsR and AHDsR slopes. Use the four envelopes independently or trigger sequentially in three separate modes.

Supplier's Notes:
The Verbos Polyphonic Envelope module is a set of four envelope generators which can be used together or independently. Cascade logic allows the four envelopes to trigger sequentially with subsequent envelopes starting at the Hold, Decay or End of the previous envelope.

Each envelope offers its own gate input, CV output and end pulse output, so it can be used in up to four-voice polyphonic patches. The three skew controls allow the times to change as each new envelope is switched on. All parameters can be voltage controlled.

Power consumption: 75mA at +12 V and 30mA at -12 V

Notes: Designed to integrate sound sources from outside Eurorack, Verbos's Real World Interface offers three channels including built-in microphones, preamps, envelope followers and a frequency detector.

Supplier's Notes:
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 gate extractor, the centre channel also has an Automatic Gain Control (fixed high ratio compressor), fundamental extractor (tracking lowpass filter), frequency detector and locked oscillator. Internal microphones are useful for introducing electro acoustic room sounds into the modular. Envelope followers can be used to have external signal levels effect parameters such as filter cutoff or level for building dynamics processors. Gate extraction allows external sounds such as metronomes, clicks, claps or room sounds to advance sequencers, trigger sounds or initiate other events. The Frequency Detector can extract the pitch of simple monophonic sounds but is also a semi chaotic CV source in the tradition of such modules since their introduction in the 1960's. The Locked Oscillator plays a sine wave at the same pitch as the input signal.
