ModSynth Control Specifications

The following table describes the range of the controls on each of the ModSynth modules.  The curve indicates how the control modifies the range:
  • linear -- means the control directly changes the value
  • squared, exponential -- means the control changes the value little when lower and more when higher.  This gives the control more sensitivity on the lower values of the range.
  • sqrt -- means the control changes the value more at the low end and less at the high end.  This gives the control more sensitivity at the high end of the range.
Note: I determined these values by examining the implementation, as I didn't have this information recorded initially.  I may not have every figure correct, so if you find values that look wrong let me know and I'll try to correct them.
