Channel aftertouch is in #630.

I think 129 is per cycle and 130 is per voice?

[paulfd]

Ok I'm lost. What do we mean by per voice or per cycle here? Barring any normalization question, these should just be like CC sources no?

Hm, yeah, I think these extended CCs are in a sense a hack. Polyphonic aftertouch would have to be per-voice. As it's each key.

Otherwise there would be no difference between Channel or Poly.

Tested CC 129 and seems it has an issue :

<region>
sample=snare.wav
loop_mode=one_shot
key=60
pitch_oncc129=1200

Sending Channel aftertouch (mono aftertouch) from my host didn't modulate the pitch :

But moving the CC 129 knob from UI does change the pitch.
Though, not sure if it's the kushview Element problem that it can't receive channel aftertouch message or not.
(I use it to host VST3)

For sfz v1, CC 129 is chanaft
So, locc129 and hicc129 are alias to lochanaft and hichanaft
Using those also cause the CC 129 knob appeared at the UI in sforzando
