I've just uploaded some new firmware for the MIDI Rocker (original and
LX) which lets you use it as a general-purpose MIDI to USB adapter for
your drums so that you can use it with software such as Garage Band or
LMS. You can get the firmware here:

I hope this is useful. I'm working on a complete re-write of the MIDI
Rocker firmware and this is one new feature to come out of it -- more
will be coming in the next week or two.
Thanks,
