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.

Once I started to get an idea of how to use it and program it, I got some excellent sounds out of it. The biggest problem is the factory patches all have a lot of extra stuff turned on etc. I am able to get quite a nice Oberheim quality out of it. I was also pleased to find it had a J wire keyboard and SSM VCF and VCA chips (first 300 made). Like others have stated, the MIDI implementation is minimally useful at best and the programming is no fun. It is indeed a wicked find.
i got one but there are only noise sounds on it.it is very old and dusty..how can i put new presets on the bit one.ist it possible?i know i can do thi sfrom a tape but what excactly do i need?
Has a warm almost analogue sound, far warmer than my DX7!
