This is Mike at Boomerang Musical Products, and here's the low down on our upcoming MIDI sync software release. It'll be called Version 3.0 and supports syncing to an external MIDI clock as well as the MIDI Start and Stop commands. When recording loops, they will be quantized to the nearest quarter note. The Stop command stops all playing loops, while the Start command plays all loops that were playing before the last Stop command.
It's technically still in beta test, but has proven to be simple to use, reliable and bug free. Email me if you want a copy with downloading instructions. firstname.lastname@example.org
This software is not a general MIDI implementation, so there is no remote control of loop or Bonus buttons.
Merry ho-ho. "
