Vintage 1977 Analog non-SRM CAT Synthesizer

via this auction

"Rare, Vintage 1977 first generation, non-SRM, “Cat” Synthesizer, from Octave electronics... They did not make a lot of these but Octave released this analog classic - the Cat - during the era of the Minimoog and ARP Odyssey synthesizers. The Cat is actually very much like the ARP Odyssey, so much so that ARP had sued them in the late 1970's for cloning their designs. The Cat is a monophonic/duophonic analog synthesizer with 2 oscillators capable of square and sawtooth waveforms. VCO 1 also has a triangle waveform. Each of the waveforms can be played simultaneously and mixed together and there are additional sub-octave oscillators on each oscillator to blend new and interesting sounds.

Features of the Cat
