Post the song for us to take a look. But first, try Options, Return to Factory Settings, Most.
Doing the Factory Reset->Most made no difference.
I guess I send it by email?
I've never done that to PGM, so my apologies in advance if I do it the wrong way. I'll try "email reply" first. If that fails, I'll email support with a note.
Ya, for sure, what Matt said, post the song so we can ty it. Some midi has embedded code which sets a specific patch (instrument) as the song plays - you therefore have to remove that if you want to set it to something different. Its a midi thing.
There's no instrument selection in at least the first few dozens of midi events. I didn't look right through, but can if it may help.
