Unleash the raw, savage growl of the 1976 classic with Cherry Audio Octave Cat – the definitive emulation of The CAT duophonic synthesizer, created in direct collaboration with its original designer Carmine Bonanno. Retaining every ounce of the original’s aggressive SSM2040 resonant filter, screaming cross-mod, and hard oscillator sync, Octave Cat now roars with up to 16-voice polyphony, MPE support, a brutal effects suite, and a classic 8-step sequencer.

From filthy monophonic leads to thick polyphonic stacks, this is the sound that powered Devo, OMD, The Prodigy, and Chemical Brothers – now supercharged for modern production.
