I’ve noticed that JUCE6 enabled polyphonic aftertouch (also called polypressure) for VST3 plugins (thank you!). Ableton Live (10.1.6) doesn’t support polyphonic aftertouch at all but I can get it to work with Cubase Pro (10.0.60) and Reaper (6.12).
For some reason it doesn’t work in Bitwig (3.2.2). I assume JUCE used a specific method that is not yet implemented in Bitwig. Can anybody cast some light on this?
