OmniSynth GM and BIAB

[politcat]

EDIT: SORRY TO WASTE YOUR TIME, I GOT IT. HA!

i've spent the morning trying to figure this one out...

I was given a copy of band-in-a-box to use with guitar students. I want to use BIAB to make accompaniment tracks that my students can play along to, but I want to use the omnisynth GM sounds instead of cheesy sounds
