Question for the JUCE team - hash generation of parameters and internal defines

To which value do you recommend me to set paramMidiProgramChangeOffset?

If I’ve understood correctly, you’re trying to add multiple program-change parameters to the plugin, one for each ‘unit’. At the moment, a JUCE VST3 has a single unit, with its program parameter set to paramPreset. It might make sense to just add the unit number to paramPreset in order to get the program parameter ID for that unit, i.e. unit 0 → paramPreset + 0, unit 1 → paramPreset + 1 etc.

If each unit is attached to a particular MIDI channel, it looks like this would imply modifying those internal parameters that handle the input CC MIDI. I have moved this discussion to VST3, Programs and MIDI Program Changes - #3 by Qfactor which has a more suitable title. I’m running out of steam right now but I’ve documented everything that I have found.
