Yep. And clarify the behavior :
I plocked all parameters (49) on a trig on track 1. I can copy it 64 times. (64x49=3146 plocks !)
But, if I copy it on track 2, Lock Mem Full warning.
So I kept 1 trig on track 1, with 49 plocks, then plocked a trig on track 2 : had the warning after 30 plocks, hence 79 plocks, 49 different parameters.
I don’t know how it is counted, it seems related to tracks.
