view Source/Mappings/Vibrato/TouchkeyVibratoMappingFactory.h @ 28:cfbcd31a54e7

First attempt at "rescan devices". Reloads TouchKeys and MIDI in/out devices. Sets MIDI in/out to Disabled if previous device not found. Does not yet handle order of devices changing.

Also fix some bugs:
-- Can now disable Standalone mode
-- Poly-AT now accounts for transposition
-- If TK device stops on error, GUI reflects it
-- Possible crash on quit should be fixed (needs more testing)
