@Lindon I can confirm channel aftertouch works fine, if I send a poly pressure message though if sounds like just all notes instantly get 100% aftertouch all over the place
@Christoph-Hart can you get us more info on how to get polyphonic aftertouch to work properly? in theory it could work like normal after touch just check if the transmitted note number in the message matches the played note before outputting it on the midi_cc node and otherwise ignore it, please let me know if I can assist in figuring this out, apparently it's important to many of us and not working properly for some years
