Note Repeat
Thanks to Dennis M. for this one:
We already know how pressing Shift + Note Repeat works, but holding the NOTE
REPEAT button and pressing MAIN SCREEN keeps note repeat on until it is pressed
again. This works on the 2000XL, but don't know about the 2000. It can be useful
if you want to use note repeat when triggering notes from a not so close keyboard
or if you need both hands.
