Thanks very much, Uncle Dave and Fran, for the replies. I'm just back to the forum here after being away for several days, so I haven't had a chance to get back to the G1000 yet.

The SVEX has two channel settings--"system & vocoder" and "key/harmony." I just looked at the display and on my last try had S&V set to 5 and "K/H set to 1. And I was coming out of midi B on the G1000. Still the SVEX wasn't tracking the harmonies on the Tune1000 files. It selected programs for certain files but nothing sounded right.

What am I overlooking here?
