Crumar Bit One

Crumar Bit One Image

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 warmest of the Bit synths, but watch for reliability with it . Later ones have other features, also good.

totally disagree with the first comment - the bit one sounds great , particularly the early SSM ones. bear in mind that this synth at excels at *soft* sounds and pads and not cutting leads , and you'll love it. It can sound quite synthex-y at times, and it's part of the same heritage. On the down side it can be unreliable and not that easy to program, but still a very nice-sounding little thing.

I heard from somewhere that Bit was actually its own comany. Were they really owned by Crumar?

Pros: keyboard velocity, unison effect
Cons: everything else. Sound, keyboard, size, quality, functions, physical layout (who the hell placed the pitch and mod wheels there??!) and it takes a long time to make anything useful with it since it doesn't even have a data entry potentiometer. You find yourself clicking buttons for 15 minutes and playing for 1
