Thanks Mac ... but I am still not getting it. Let me try one more time to make sure I'm asking my question precisely.

You are saying that every Real Track instrument is (or has) also a specific, individual Real Track style associated with it (with a prechosen accompaniment from other Real Tracks)?

And, if so, when you open that style, can you change any band instrument with a different available Real Track instrument ... as you can with midi voicing in BIAB? Or?

And is track freezing part of Real Track style ... so you can generate a song from a style, freeze the tracks you like and then open another style to change some of the instruments?

Finally, is there a list somewhere of which original midi styles permit Real Track substitution?

Thanks.
