[PD] pd-based procedural chord progression database..

[Chuckk Hubbard]

Two things come to me right away.
One of the things Bach did was to start using certain notes that
implied a key change before there was any indication of momentum
towards a key change.  It's easy to work a Bb into a theme in C
without giving too much away.  Then when it happens, the change sounds
like it fulfilled some subtle destiny.  I have *no idea* how you could
do this with Pd.
You can get away with a lot of little borrowed progressions with jazz.
 Any chord whatsoever can be preceded by a dominant 7th, or a tritone
sub for a dominant 7th, and that in turn can be preceded by a minor
7th, or a tritone sub for that, and so on.  You could actually have
lots of momentary forays that would end up returning to the original
key.

Far easier to come up with ideas for it than to actually patch them...
