Crumar Bit 01

Crumar Bit 01 Image

The Bit-01 is a 6-voice programmable polyphonic analog synthesizer with digital control. It is essentially a rackmount version of the Bit-99 keyboard synthesizer. It has two analog oscillators per voice that are digitally stabilized and controlled. Also on-board are resonant filters, ADSR envelopes and two LFOs. Fairly easy hands-on editing and a layer/split function make this a very useable poly-synth! The MIDI implementation is basic but useable and there are 99 memory patches. The Bit-01 is well suited for studio use and in all forms of electronic music.

Not the greatest analogue. But it has a character of its own.
Used it mainly for bass sounds and some brassy type of lead sounds back in the early 90;s.
I remember that it was impossible to make a warm string pad from it. Maybe it's because of the DCO;s? I don't know? It's even worse than the original all digital DX7 for that.
The good LFO implementation makes it good for Fx, especially with filter destinations where the resonance is set at a higher level.

Poor MIDI? It has full MIDI with sys-ex like the BIT-99. It's not a module version of Bit One. It's a module version of Bit-99.

I Agree this unit is deliciously quirky but great sounds with detuned oscillators real rich brass sounds. Real problem is absence of midi out, you cant save your own voices unless you grapple with the archaic tape interface-nasty. This site http://www.pierregander.com/bit/index.html has some voice banks but not updated since 2001

What i love is that its all a bit flakey ? the osc are chessy - kind of unique and novel , different combinations seem to change the basic osc outputs waveforms ? its odd , add to that the lfo x 2 and the fact you can combine these in cool ways and its a very cool synths.The lfo go so fast they cant be heard ! and nice and slow , theya re very 'wavey gravey ' as far as lfo's go , lovely and warped....What gets me is that just a basic 1 osc waveform in this thing sounds good , unique , has character , stack another to a 2 note chord and then apply 2 x subtle pitch mod lfos and its cheesy 70's / 80's all the way , the filter is nice , warm and organic , self resonance is possible and will keytrack in the weirdest possible ways , this machine can do strange stuff you would expect it to .
