initial version for ableton 11

Mixer button 9 = OverDub
Shift + Mixer button 9 = Automation record on/off

Shift + Rec = Metronome on/off
Shift + Play = Undo
Shift + Stop = Stop all clips
Shift + Ffwd/Back - next/previous device

Shift + Loop now enters "alternative assignments" mode.
Differences:
is that mixer buttons are permanently armed (like the shift is pressed)
if you press Shift and arm the track, it will NOT me selected automatically

It is very good for performance when you need to quickly switch instruments and only have one left hand or right hand available as the other is ready to play

Shift + Clip buttons are now clip stop
