Bernie, sorry... Yes my email has been acting funny lately..

I disagree with Fran about routing to separate outs. What you REALLY need to do is create a MIDI Set that routes that particular Part to External. Read the manual carefully in the section about MIDI SETS, and see if it doesn't make sense. After you have set that up so it works, you can LINK the MIDI SET to a particular UPG, so call up the UPG and the routing is already done...

Routing Parts you don't want to hear to separate outs will make the G70 still play them (eating polyphony) even though you can't hear them.

You could also set up a UPG/MIDI SET combo that routes say UPR3 to the top manual channel in the Nord, and LWR2 to the bottom manual, and have a dual manual B3 setup if you want that, too..

Personally, I'd post at Roland-arranger for more detailed and informed help (we have several members already doing what you ask)....
