I think there's still some new code to write.
The style metaphor in place seems too cumbersome.

instead of 5000 styles perhaps PG Music could experiment with a new approach to style.
A continuum based on a particular style, not 100 different minor permutations of said style.
Most of which never get used.

For example,
Start with a style - lets say Rock Ballad.
Create tracks in BIAB with 3 or 4 musicians (Drums, Bass, Keys, Guitars) in a basic rock style.
Let user adjust a parameters for each musician to get some groove they are after.
Some of us currently do this in a very manual way in BIAB
Example- Select bass player 1, regen, listen. Throw away, Select bass player 2, regen Listen
Lather rinse repeat until Eureka! , or your will to live subsides and you live with what you have.
Or you do midi.



AAPL does some of this in session musician.
Its perhaps but a taste of the future.
Its not well developed but there are parts of it that are compelling. The drummer for example.
If only they had more Jazz/Latin Drummers.

PG has a head start on this.

Anyway,
