I think that everyone here acknowledges the wonderful musicians that play on the RealTracks, but that acknowledgment should stop here, in these forums.

If you use BIAB or RealBand for fun and your own amusement, sure, go ahead and let people know how it was done; that's not a problem (as I see it, anyway).

BUT, if you're making demos to send to record companies, or publishers, or for public sales, explaining how you did it all yourself with these products will distract from the professional purpose of the recordings. It's analogous to a magician explaining how he does each trick. It cheapens/destroys the illusion.

All this is just my opinion, but you might wanna consider it if you're doing this professionally. You may not be playing the music, but your creativity is shaping the output; you are the producer.
