Receive PC messages via GP Relayer to change Song in Setlist

I’m using Studio One with Gig Performer for live shows—Studio One handles backing tracks. I’d like Studio One to send Program Change messages to Gig Performer to step through Songs and Song Parts. Studio One is sending Program Changes on Channel 12 to GP Relayer, and Gig Performer is set to receive them under Global MIDI > Program Change Control. The messages show up in a MIDI monitor on the GP side, but they aren’t changing Song Parts as expected. External MIDI devices work fine, so I may be missing a step—I have a feeling it’s something basic and obvious (maybe create a dummy midi device?), but I’m not sure.

This is on a Mac, GP 5.1.6 and Studio One 8.0.3.

Have a look at this thread.

darn, thanks. I’d been using the search function in the forum, but never came across that thread. I’ll have a look and try the stuff out!
