With the great firmware update by Bob Grieb (tauntek.com) it's finally possible to control all parameters of a Crumar Bit 01 via MIDI. This MD layout has been tested with a Crumar Bit 01, but should in theory also work with a Bit 99 and to some degree also with a Bit One. Since I only have a Bit 01 here, I couldn't test it myself, but comparing the CC maps of the three synths they look basically compatible (Bit 99 does not have Detune / Noise though, but CC's are otherwise identical).
Note: To use this layout please ensure your device is in Lower, Edit (Address) mode. CC's are only accepted in this mode. Please also note that you will exit this mode when changing a program (e.g. via the Up/Down steppers in this layout). So, after changing a program you'll need to manually enter the Lower, Edit (Address) mode again.
