I'm trying to use band in a box (version 10) to generate basslines for my piano playing. However, sometimes the bassline generated does not fit the chord. For example, when the chord is G7alt (or G7#5#9 or G7b9 -- it doesn't seem to matter how I enter it), the generated bassline will include the natural 9 (A, in this case), which is obviously wrong. Once it even played a natural 3 over a minor chord. Any suggestions on how to fix this will be appreciated.
