Just going through the event types in VST3. I don’t see MIDI CCs , PitchBend or Channel Aftertouch!?
CC1 (modwheel), channel aftertouch and pitchbend are “essential” in synth presets , we have thousands of presets with modwheel / aftertouch or pitchbend assigned as performance controls. if the argument is -use automation -, NO that is NOT the answer for synths. Also, in MPE, they + CC74 are essential as well.
Just my 2 cents…
