Here's a simple patch that makes RG send an MMC LOCATE command when
the playback position is reset to 00:00:00.
Now clicking the "rewind to beginning" button in the RG transport
rewinds my multitrack too :-))
Is resetPlayback always sent when the transport jumps about? If so, I
could extend this to send LOCATEs to the multitrack at other times.
