Hopefully you can listen to the solo, and comment on it. And let me know if you stick by your comment that "Band-in-a-Box is bad at generating professional guitar solos".
Peter, you have no idea how much I hope I was wrong about this. BiaB is the most efficient music software I have ever used, and generating a guitar solo with a virtual guitar instrument is a painful learning curve.
My problem with BiaB generated solo is, it's good, but not perfect, so you need to partial regen. When you partial regen, for musicality purpose, you need to regen a full bar, or at least a full beat. The result is always very close, but not the best.
The solution would be, directly comping the source material in the RealTracks folder. But I can't open and read .bt1 file, and therefore I don't know which chord is referred to which bar in the original recording. Hope you know what I'm talking about here.
