I am finding this issue playing live….
If I release a key while aftertouch is pressed (most noticeable when aftertouch is assigned to mod wheel or oscillator pitch modulation)…often the next time I press the key that aftertouch is still engaged, when it should not be.
It seems that sometimes the note off arrives at GP prior to or simultaneously as the aftertouch zero message and the aftertouch message is being missed. Happened 3 times last night during a performance on different rack spaces.
Pressing the key with aftertouch clears it.
I did check to make certain I did not have ‘momentary to latch’ flag flipped.
