Ive noticed this too. it seems there are still heaps of problems with re-trig… aftertouch affection still doesnt work in chromatic mode when re-trig is attached. and the fact that it doesnt work still when recording it in live mode

Re-trig curve works really well when you set it in grid recording mode as a p-lock.

Also try playing with the pads velocity and aftertouch settings it makes the curve more noticable when playing it live !!
