Following what I have read here and here, can someone please tell me what callbacks / parameters should I see being called / changed in response to a MIDI Program Change sent from the DAW?
My plug-in is an audio plug-in that also receives MIDI (but does not emit it)
Any repeatable procedure to see it triggered in any of the main DAWs would be greatly helpful.
I have tried creating the default audio plug-in project with Projucer and increased the value returned by getNumPrograms() to 128, added a member variable to hold the current program but none of the program-related callback seem to ever be called, neither in Cubase nor in REAPER (I am developing on macOS mainly).
Has someone been able to make it work somehow? Any pointers in the right direction?
For the JUCE team, is this even possible in VST3
