Ps....

What I havent looked into yet is exporting the finished real track multi riffs to midi files, so that I can contour the phrasing some in a midi editor.
If that is possible that would be another level of user control that enabled some degree of personal phrasing.

Also...I tried this approach with EZK but I could not arrive at anything that sounded unlocked from the chords and not stiff. I chopped the chords down to 1/8 notes in places and introduced suspended 4ths and add9s and some major 7ths but never got anything that sounded as natural as using BIABs multi riffs with some cutting and pasting.
