Description | 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. |

| Velocity |
As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. |
Aftertouch |
Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel. |
| Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise. |
