I am working on a new setup where I control my two H9s by MIDI control messages. MIDI CC has a range of 0-127, whereas most H9 algorithm parameters have different ranges and units. I was wondering if there is a table of some sort that matches MIDI CC values to real parameter values …
I like the way that you think. ‘Snapshot’ MIDI is more forgiving than a barrage of continuous control.
As you’ve stated, the ranges are scaled differently for each algorithm, sub-type, and parameter. I started mapping out each one in the PitchFactor (which was daunting enough). But when I Maxed Out my H9’s …
Now, I figure out the CC value equivalents as the need arises. If it helps, there are a few ‘tools’ that I’ve used to match CC value to parameter position. Create a DAW or sequencer MIDI file, and run it through the H9. Write in a CC value from 0 – 127 at every measure. Start & stop the sequencer at the matched parameter value.
I’ve found it easier now to use a MIDI keyboard switch or encoder with a ‘step’ feature (Novation), or the big ‘Knob’ on a Lexicon MPX-1. Hook the 2 units up, dial in the values, then jot them down for future reference.
Again, it’d be algorithm + sub-type dependent. For the HarModulator, it’d be CC Value 66 or 67. For the H910 / H949 Chromatic mode, it would be CC Value 90, 91, or 92. Other algos or modes will be differing values.

That would be 30% wet, in the PitchFactor algorithms. As far as I know, the Mix values stay consistent across the H9 algorithms, but I haven’t checked out every single one. If you have a specific algorithm parameter in mind, I may already have it ‘mapped’. Or I can help you to get there.
Some parameters with 1000’s of possible values (like unsync’ed Delay) can’t be nailed exactly by a coarser 0-127 MIDI CC value range. Pitch Bend supports double-precision accuracy … at least 12-bit, if not 14-bit.
