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.

Don't expect any virtual analog supersynth, it isn't but it does have a "life" of it's own. Was designed by chap who did elka synthex
I've bought this (too) cheap, wellknowing it was out of order. Does anyone know of a Bit One-manual download, Diagram or a repairshop in northern europe?
Truth is that is instrument has character and sounds phat when played in double or unison mode. Dont let the presets fool you, you can get quality sounds with just a little bit of programming.
I would not recommended this synth to beginners or to people that want to make everything with just one synth.
The only drawback I see is the poor midi implementation and the button style of programming.
If you can find one, just grab it !
