Peter:

Thank you for the reply.

I'm not looking for a whole new instrument. I understand that the tracks in a given style will necessarily be similar. There are two things that don't seem to be working as they should:

1. Some of the tracks generated by BB consist of perhaps 2 or 4 bars that are repeated with no variation at all, for a full song--3 or 4 choruses of 32 bars each, e.g. If I would hear 10 different patterns in the rhythm guitar track of a 4-chorus song, that would be what I would expect, but not what I often (though not always) get.

2. Often, when I hit the play button and expect a different performance, some of the tracks do not change at all. I've brought them into Sonar, laid them up in adjacent tracks and played them, both serially and simultaneously. There are no differences.

As I said, neither 1. nor 2 are the case all the time, but often enough to be frustrating. Since I'm not a guitar player, one of the great benefits I expected from BB was a source of useable rhythm guitar tracks. While I've found a few--especially in RT--many times I can only get one, overly repetitive track.

I can't do this right now, but I will go to the program and try again. If I get more of the same, I'll send you the names of the styles, the changes, the MIDI or audio files, and anything else that might provide a clue.

Thank you again for your suggestions.
