This is a fascinating thread. Being a new user, I have been slightly disappointed with the BIAB melodist also. I agree that it generates too many chords. And the chords are too jazzy (unless you are composing jazz). Some of the simpler virtual composers generate lower chord density. EZ and MOR are adequate, and Jimmy Buffet doesn’t get too crazy. But the results don’t really sound correct for the modern pop genre nor do they sound novel. Scott Joplin is fantastic!

I have a program called Jammer Pro. The authors haven’t done anything significant with it in 10 or 12 years. They still have the same demo midi files on the website since 2001. Jammer Pro has a very excellent chord progression generation algorithm. It lets you adjust parameters like: the pace of the chord changes, starting and ending on the tonic or fifth, the monotonic and diatonic flavor, and the percentage of what they call pop, breezy, blues and jazz chords. I am often amazed and inspired by what Jammer Pro spits out. You still need to use your judgment though.

I would like to see BIAB allow the user to control some internal parameters and improve the algorithm. There would be less fix up required later in the composition procedure.
