BEHRINGER / CAT

CAT is a duophonic analog synthesizer. It reproduces classic tones reminiscent of classic electronic music.

Dual VCO design allows for the creation of very thick sounds
Faithful reproduction of the original “CAT SRM II” circuit, a fusion of transistors and JFETs
Pure analog signal circuitry with authentic VCO, VCF and VCA
Four variable oscillator shapes (sawtooth, triangle, modulated pulse, and sub-octave square) for ultimate sound
Duophonic / paraphonic mode allows independent control of both oscillators
Oscillator and filter can be modulated from 6 different sources with 2 modulation depth attenuators
Full analog sine/square wave LFO
Two analog envelope generators for VCF and VCA modulation
White noise generator dramatically increases waveform generation variation
16-voice polychain allows for up to 16 simultaneous voices when multiple synthesizers are combined
Module fits in standard Eurorack case
47 controls provide direct access to all parameters
External audio input jack for input and processing of external audio
External control inputs and outputs (high note CV, low note CV, gates, filters, etc.)
USB/MIDI implementation with selection between MIDI channel and audio priority
Classic filter design (low-pass peak/resonance) with self-resonance capability
