Octave was a New York based company, they have actually only produced 2 synths (and 1 controller) around 1976-1979. Then they merged with Plateau Electronics, becoming Octave-Plateau, which released the mega Voyetra-8 synth.
They did actually survive, changing the name to Voyetra, releasing music software, and eventually became Turtle-Beach! They're are still around, y'know!

Octave's famous synth was the ''flagship'' The Cat, usually known as Octave CAT.
The Cat has went thru a few revisions - Original, SRM (Series Revision Model) and SRM II.
They released the Kitten, in 1977.
The Kitten is a single VCO version of the Cat (Cat being dual-phonic), basically half the Cat, with the same 24dB/Oct LP Filter.
However, I have not seen info on the web on the Kitten II (or any mention of it).
This Kitten II seems to be a later or the last revision of the Kitten, manufactured under Octave-Plateau.
