Some as yet unreleased new features actually make the
record_or_overdub command even more suitable for "one button
looping"...  if there is nothing in the loop it starts Record, then
stops record.... then when hit again thereafter it starts/stops
Overdubbing on that loop.  Do a double tap and it does an Undo.  Hold
it down (a long-press if you have note-like bindings with separate
press/release ability) and it clears the loop.  If record and overdub
covers your looping, you could just set up a button on your controller
for each loop bound to this.  Look for it in the next release.
