Actually, it seems a bit more odd...

When I open up a new song, all non realtracks play with the same instrument.. (I didn't notice this because I have been working with realtracks over the past two weeks...

I can change the sounds correctly by using the plug-in to select Sfz or ST on the thru track

If I choose Apple:DLSMusicDevice or Apple: MIDISynth I still can't change the songs...

It is as if my choosing DLS in the ports window routes it to a synth that I can't see or change...

As I am new to BIAB Mac, maybe there isn't even an internal synth on my IMAc...one doesn't show up on spotlight...I wil go and see if there is something I need to get from the apps store...
