Yes I think real tracks are nice in their own way but why don't U generate MIDI data from them, MIDI data is so much easier to tweek and modify, generally I never use straight Band in Box midi, I use it for the drums and for variation but something original is always implanted inside my Band in a box MIDI tracks, I use Karma, Korg Karma is not hassle free but it will support Quartal Harmony and other exotic stuff that band in box can't handle, I realize I may be outside mainstream a little, but from a academic perspective I think my ideas have real value. I could paste in samples of what i am talking about but I don't think that is allowed. Some of my harmonic ideas come from Mick Goodrick which is sort of like Allan Holdsworth where traditional chord symbols don't really work, many of the chord do not contain the root because the idea is the bass supplies the root. Some of the ideas are explained in (Generic Modality Compression) Creative Harmony by Mick Goodrick and Tm Miller, but there is some overlap with the concepts of Allan Holdsworth and Quartal Harmony and the concept of chord cycles. There is a way for Band in a Box to support it, I am programmer, I wrote a program that makes pdf diagrams (dots on a fretboard) of my concepts that could be translated to Midi data.
