Great.
One thing I've wondered also, is if it would be possible, to have some on screen sequencer control, via Max somehow.
But as I'm writing this, I guess, you could just make your own sequencer in Max spewing out midi notes. Should be possible to convert this data to the text file, that the Microbrute is using, and then export the sequnces made in max to the micro brute.
Nice machine for sure.
