OK,
Right now I have it like this

AR/GLOBAL/MIDI PORT CONFIG/INPUT FROM MIDI
AR/GLOBAL/MIDI CHANNELS/PROG CH IN CH 11

OT/PROJECT/SYNC/PROG CH Send checked, Channel 11
OT/PROJECT/MIDI/CHANNELS Auto Off

This allows me to use a midi track on the OT set to channel 11, and the Program Chg # on that midi track determines the pattern number on the AR.
Problem is, that prog Chg # is attached to the Part.

This is where I get confused. How do I make the AR follow OT 1to1 pattern wise?
