OBERHEIM SYNTH

I have a dilemma.

Maybe an easy thing for you super matrix pros.

I'm currently programming all of my midi songs in Cubase.
I have a hardware sequencer that accepts standard midi files, so
transferring any data is no problem.

My question is, how do I assign a midi track to correspond with a
patch on the Martrix 6?  

For instance, if I want to use patch 22, what program number would
that be?  22?  Do I just select a program number, or do I select a
number + a bank... or do I modify sysex information in Cubase?

The worse case scenario is simply assigning each midi track to the
appropriate channel in cubase, then manually changing the patches live
on stage.  But my goal is to have all of my songs pre programmed with
all of the program change info, so as each new song loads, the matrix
6 changes it's patches automatically without me having to change them
manually.

Any help is appreciated.

Thanks!
