Sustain/latch functions #22
Description
We could dedicate a button on each controller to sustain so that the user can keep a note going after they have already played it.
X/A seems like it could work, as there is no need to use the note repeat function (analog stick) at the same time as the sustain.
Most sustain pedals do something like: If the user plays a note when the sustain is active, delay the note off message until the sustain is released.
A latch function might also be nice, but it's unclear how it could fit in. Maybe the user could switch between sustain and latch using the analog stick?
Latch would cause the played note to stay on until it is played again.
