I don't know exactly, but I'll give an educated guess:

  There are 16 bytes per patch.  Presuming the bytes are stored in RAM in 
their hardware address order, you have:

  1st byte: Effect Speed/Intensity knob
  2nd byte: Filter Fc knob
  3rd byte: Filter EG intensity knob
  4th byte: Filter Q (resonance) knob
  5th byte: Attack knob
  6th byte: Decay knob
  7th byte: Sustain knob
  8th byte: Release knob
  9th byte: Filter keyboard tracking knob
 10th byte: PW/PWM knob
 11th byte: PWM speed knob
 12th byte: MG (LFO) speed knob
 13th byte: MG delay knob
 14th byte: MG level knob

 15th byte: switch bits for VCO oct (2 bits), waveform (2 bits),
            subosc mode (2 bits) and MG destination (2 bits).

 16th byte: switch bits for EG VCA mode (1 bit), effect mode (2 bits),
            attenuator (4 bits).

  I don't know exactly which bit values mean which setting for the
switches.  Best way to figure that out is just a little trial and error.

  The 14 knob values are at 8-bit resolution.

  Hope this helps,

Crow

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
