We should probably keep it simple so it's not so overwhelming for
Colin (I still need to talk to him about this).

I'd say the most important aspects would be;

-Midi Out in Pattern Write Mode.
-Pattern Select Write Mode.

This is still "up in the air", but having the firmware dumped would be
the first step.

Cheers

Ryan
