In certain hosts, all MIDI data that is not note related (on/off, velocity) will not pass to the plugin. This even includes pitchbend and the modwheel, which hinders a lot of functionalities in my plugin.
The hosts I found so far which do this:
- Samplitude Pro X4
- Reason (which I don’t support anymore, because VST2 and stuff)
I tested with U-he Diva and it seems to receive pitchbend just fine in Samplitude - so my conclusion is this is about my plugin. Is there some flag I missed setting which makes the host think I don’t want these events?
