Crumar Bit One

The Bit One is a 6 voice programmable polyphonic analog synthesizer with digital control that rivals the Roland Juno-106 synthesizer. The 61-note keyboard is equipped with velocity which is a rare option among similar synths! The 2 computer controlled oscillators, 6 voltage controlled filters, 6 VCAs and 2 LFOs each per voice, easy hands-on editing and a double/split mode keyboard make this one phatt analog polysynth! A few let-down features of the Bit One stand in the way of an otherwise great synth. The MIDI implementation is useable but poor and there are only 63 memory patches. The Bit One has been used by 808 State and Cirrus.

The one I had was on it's last legs, and by the time I reluctantly parted company with it, the oscillators had drifted so far out of tune they'd made it almost unplayable. Yes, the MIDI was dreadful (omni mode, anyone?). It didn't have the fat, squelchy filters of the 106, but it's range was more versatile - and the sounds more usable (even today).
Without doubt my personal fave from the 80's (and 90's). If only I could find one for sale now..!
..anyone?
Has any one the view(picture, manual ) how to create some factory or other interesting patches?
