John, the style I'm starting with is M_ANSWR1.STY, which is all MIDI, I think. A couple of instruments are blue -- Piano and Strings 2. So the blue tracks are "MIDI Super" tracks. Will that make a difference? The style I want to switch to, which I chose on a whim, is also straight MIDI: ETERNAL.STY.

I have all the instrument tracks frozen. And I was just hitting "Play," not "Generate and Play." So I'm gonna try unfreezing them right now, and then hit the Regen button.

Huh, strange. I had selected different instruments, but the only actual change occurred with the drums. All the other instruments stayed the same. So then I tried it with the box clicked, which sez to send patch change with style change. That didn't make any difference either. Odd that the drums changed, but nothing else did.

So, strike one.

Dioechoto, what you describe is the way I normally operate. I prefer to save my BiaB arrangements in small segments -- individual tracks, that is -- and import them into my DAW so that I can combine them how I want. Trying this "feature" in BiaB is more of a lark, really. I was thinking that, since it was there, I should give it a try and see what happens. Not impressed so far. So I guess I'll go back to the way I was doing things before until or if I can figure out why BiaB doesn't want to cooperate. Absolutely the buggiest software I've ever spent money on.

Best,
Michael
