Rhodes Chroma Polaris

I'm currently programming all of my midi songs in Cubase.

I have a hardware sequencer that accepts standard midi files and
converts them to my sequencer language, so transferring data is no
problem.

My question is, how do I assign a midi track in cubase to correspond
with a patch on the Chroma Polaris?  

For instance, if I want to use patch A6, what program number would
that be?  Do I just select a program number, or do I select a number +
a bank... or do I use 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 polaris
changes it's patches automatically without me having to change them
manually.

Any help is appreciated.

Thanks!
