Emu XL-7 & MP-7 User's Group

I have Cakewalk Home Studio setup so that certain MIDI channels
matches a certain instrument on the XL7.  How do I set up the XL7 so
that it receives the instrument that I want to play from a certain
Midi Channel?

For example, I have midi channel 1 setup to play instrument 1 on the
XL7 and midi channel 2 setup to play instrument 2 on the XL7.  The
problem I am getting is that the XL7 only plays the preset that is
mapped on the current track/channel on the pattern regardless of what
MIDI channel I have selected on the external sequencer.

Any help?  I know the XL7 can be setup as a sound module but I think
it's pretty lame if an external sequencer can only play one instrument
from it at a time.

Any help would be greatly appreciated.  Thanks.
