Re: x0xb0x and the tr-606
if you want it to act as a converter - you have to use midisync mode, which means "no input midi notes" and "use the x0xb0x sequencer"
and yes, there IS a way to do what you need, but it will require a firmware mod, which you can do yourself if you have some C programming knowlage
get the x0x firmware source code, find the MidiPlay code (which reacts to midi notes) and merge it with PatternPlay (midisync mode)
We are here too: irc.freenode.net >>> #x0xb0x
