Shortly after the first synthesiser in the BIT series, the BIT ONE, the BIT 99 and its rack version BIT 01 appeared in 1995. Shortly afterwards, Crumar developed the little-known BIT MMK Midi Master Keyboard with 72 keys. It was launched on the American market in an identical design as the Unique DBM. 

Like all BIT synthesizers, the BIT MMK is a 6-voice analogue synthesizer on a DCO basis and is equipped with 2 DCOs, 2 LFOs, 1 VCF, 1 VCA and 2 ENVs per voice. All waveforms of the DCOs can be activated together. The six-octave keyboard with 72 notes is sensitive to both attack velocity and channel aftertouch. It has three keyboard zones, each of which with an own MIDI channel, patch numbers (1-128) and transpose value. The right zone has a programmable lower limit and the left zone a programmable upper limit, the center zone can be turned off for a three-way split. It also has 13 MIDI channels and a stereo mode that allows the sound to switch randomly between the right and left channels, three assignable controllers: one wheel, a footswitch and a footpedal. The designers have given a 4000-note sequencer, with four polyphonic tracks and both real-time and step-time recording capabilities. (source: muzines)
