If you play a note and then decide to hold it, you have to release the pad then hold down Shift and play the note again. It would be nice to be able to press Shift while holding the note pad and also have it latch. So latch can be shift->pad but also pad->shift.
What should this feature achieve?
Better spontaneous playability without discontinuity of the notes.
You can do this already if im understanding you correctly.
There’s 2 ways to latch notes right now. Hold shift and then press a pad or pads. The other option is hold down the pad or pads then press shift and then while shift is held lift your fingers off the pad or pads and then off the shift button.
