Octave The Cat
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.
The original Cats were purely monophonic, but then came the SRM update which added the duophonic (2-voice) capability. The Cat (SRM) has a 2-note sample-and-hold feature for each voice too! The Keyboard can be switched between 2-voice (poly) and 1-voice (mono) modes. In mono mode the 2 oscillators can be stacked for a rich mono-bass or mono-lead synth sound. Poly mode limits the richness of the sound because each VCO becomes a separate dedicated voice. In this mode you can create slightly more complex melodies with overlapping notes or very basic pads. The sub-osc plays at an octave below the actual note played which nicely adds some warmth or bottom to your sounds. It has been used by The Dust Brothers, Chemical Brothers, Devo, Rod Argent, David Bedford, Lyn Berger, Dave Greenslade, OMD, Loaded and Mixmaster Morris.

The synth has been rather stable. I purchased it about 2 years ago. First thing I did was run it over to my synth guy for a nice tune up. He told me that besides for cleaning a few contacts, tuning the OSCs and replacing a few things here and there, that there was little else for him to do (I.E. I could have totally done it myself. He was also extremely surprised by the synths capabilities.
As a bonus I also got the manual/schematics/etc. in the original envelope sent by Octave post marked 24, Aug. 1983!
I would also like to refute the "Odyssey clone" meme which is prevalent but quite wrong. This thing's sound put the Arp in the dust.
