Trigger
each sound is assigned to one of the 12 available trigger inputs based on custom DYNAMIC ARTICULATION system technology.
Some dedicated trigger parameters matches the drummer playmode behavior:
- sensibility adjustment
- 8 velocity curves
- decay time and the
- crosstalks: a threshold gate from nearby pads vibrations
