-
A*B+C
Voltage-Controlled Voltage Processor. Two-channel utility that multiplies two input signals (A × B) and adds a third signal (C) to the result. Supports ring modulation, linear VCA, mixing, attenuation, and CV processing.
-
BF-22
Dual Hi/Low-pass Sallen-Key VCF inspired by the early MS-20, with two independent channels, CV-controlled cutoff and resonance, attenuverters, and a Link switch for series routing.
-
Hexmix VCA
Six-channel VCA with variable response curve (exponential through linear to logarithmic), with summed mix output. Can be used as a six-channel mixer or six independent VCAs.
- I4 – Instrument Interface
-
Mixer
Utilitarian audio and CV mixer that combines up to four audio and/or CV sources into one output, with independent manual level control. Can be used as a four-channel mixer or as two separate two-channel mixers depending on connection. DC-coupled with LED signal indicators.
-
Muxlicer
Muxlicer is an eight channel, CV addressable bidirectional analog switch and gate generator, divided into three main blocks: Digital Step Controller, Gate Generator, and Analog Switch (Mux/DeMux).
-
Noise Plethora
Multitimbral noise monster with three digital sound generators followed by three analog multimode filters. First two channels choose from dozens of algorithms with two CV controls each; third channel has gritty noise, white noise, and filtered outputs.
-
Oneiroi
Experimental stereo synthesizer for ambient pads and drone-like soundscapes. Built on the Rebel Technology OWL mk3 platform with 24-bit/48kHz stereo audio (32-bit internal processing). Features 3 oscillators, 4 effects (filter, resonator, echo, reverb), a 5-second looper, self-modulation, and a randomizer.
-
Pony VCF
Space-conscious lowpass filter and volume processor. A combination of VCF + VCA + Mixer that lets you mix three different sound sources and shape their tone and levels. Built around the SSI2144 FATKEYS chip with temperature-compensated Q and frequency, and resonance-compensated volume.
-
Rampage
Dual voltage-controlled integrator/function generator based on the Serge/Buchla ramp generator concept, with slope detectors, analogue logic functions, and combined outputs.
-
Sampling Modulator
Multi-function module that lies somewhere between a VCO, a Sample & Hold, and an 8 step trigger sequencer. Can function as a sequencer clocked sample & hold, analog down-sampling effect, sampling modulator/shaper, 8 step trigger sequencer, and unusual V/Oct VCO. Uses a temperature compensated ramp core VCO with more than 4 octaves of tracking.
-
Spring Reverb
Versatile spring reverb module with two voltage-controlled inputs, one routed to mix and tank, another straight to tank; CV control of MIX; MIX and WET outputs.
-
STMix
STMix is a four channel stereo mixer in 6HP. It can work independently or as expansion of the Hexmix module via the six pin connector located in the back. The module includes an extra stereo input (Aux) without attenuation that goes directly to the output.
