Thanks, I never did finish up a ‘definitive’ reverb CC chart.  Yes, they are all slightly different, depending on the algorithm.  But what I did focus on was an easier route to use for diagnostics in the MC6 Pro.

  • Basically a variation on the MPX-1 “Knob” or Novation “Step” switching.
  • Use CC Value Scroll to step through 16 values.  Increase & Send one Step per switch Press.
  • Program the 6 switches in a Bank to cover 16 values each (0-15; 16-31; 32-47 …).
  • Two more Presets in a 2nd Bank to cover all the possibilities (…96-111; 112-127).
  • Of course, with the CC Number mapped to your H90 target parameter (most often Decay, in this scenario).

That way, you can zoom in on the exact CC value brings you to the next “zone”.  In your particular experiment, probably any value 100-107 will hit INFINITE; 108-127 will FREEZE.

With many of the H90’s non-continuous parameters (less than 128 discrete positions), any CC value within a small range will give you the desired result.

A MIDI Monitor will be your best friend here.  Any one will do; readout in decimal might be more forgiving than hex.  I assume you’re using the Morningstar Editor app.  There’s a linked online MIDI Monitor there.
