Cherry Audios Octave Cat synthesizer emulates The CAT duophonic synthesizer unleashed by Octave Electronics in 1976. Developed in partnership with The CATs original designer Octave Cat ($49 MAP/$69 List) retains all the growl of the original hardwares fat savage sound and replicates its aggressive resonant filter. Octave Cat features the flexible modulation screaming audio-range oscillator cross-mod and fierce oscillator sync of the original hardware and extends it with expanded polyphony a robust integrated effects suite and a versatile dual-step sequencer.

1976: The Year of The CAT

In the early 1970s portable synthesizers were a rarity and only a select few musicians could afford the legendary Minimoog or ARP Odyssey synthesizers. Recognizing this a small group of engineers in New York led by the brilliant 22-year-old Carmine Bonanno decided to shake things up and create affordable synthesizers with innovative features giving birth to Octave Electronics.Drawing from his own designs for a modular system Bonanno and his team set out to create a synthesizer that was not only accessible to up-and-coming musicians but also boasted groundbreaking features. The result was The CAT synthesizer an elegant and easy-to-program monophonic/duophonic synthesizer that offered an innovative combination of features including cross-mod configurable sample and hold extensive modulation dual sub-oscillators combinable waveforms two types of oscillator sync and a lowpass filter with uniquely powerful resonance. Even more revolutionary was the 1976 introduction price of only $599 – a game-changer for musicians who couldnt afford more expensive alternatives. It also caught the attention of more affluent musicians who praised its exceptional performance and versatility. Some of the biggest names in electronic music have used The CAT including Devo Orchestral Manoeuvres in the Dark Dave Greenslade Split Enz (notably for the keyboard break in their hit track “I Got You”) and more recently The Prodigy and The Chemical Brothers.
