"Arp Odyssey Mk. I 1972, full patch points + Cirocco (C.M.S.) mods

Mods too many to list, but include (highlights):
Full patch points -- all main section outputs and all slider inputs
"Turbo" envelope switch, for true snappy (2600 style) envelopes
LFO free run
Back panel CV/gate controls
External audio input
A full set of mods can be seen from the picture. Mods were performed by #1 worldwide Arp tech Phil Cirocco (the guy who fixes/restores 2500's).

I should mention that another design quirk of the original Odyssey -- the delay between VCA and VCF gate times, has been eliminated!

Without this critical fix, no matter how fast the envelope times, it would have sounded slow due to the VCF gate delay. Not so here, the envelope is ultra-fast with the "Turbo" setting, and also sounds better and cleaner with the normal setting. This is what is meant by "true 2600 style envelopes" -- multiple coordinated modifications here really take this synth into a completely different category.

What you get is the 'best of both worlds'. You get additional features and sound of the early 1970's Mk. I Odyssey (much warmer early 1970’s oscillators, sweet filter resonance, hard sync), with the back-end snappiness and sonic character of the Arp 2600. On many patches the result actually sounds better than the stock 2600."
