Description | 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. |

| 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. |
