I totally agree with Matt and Bernard.

And that was the reason for this thread, I think. If you want a certain chord, like that F#min11, bass and piano should reflect that very particular choice.

A lot of “modern” jazz cats write very exact chords (Kenny Wheeler writes down every extension, as do Pat Metheny and Joshua Redman). No guess work, cause they want specific harmonies to go with the melody.

I know PGMusic could help us out here. Sure, it would limit the variation for very basic chord charts, but it would add to the experience.

In the New Real Book some standards have alternate changes (as played by Herbie Hancock or Bill Evans). Bob Norton wrote them out for Band in a Box, very detailed and professionally done. Sadly, biab can’t play them properly and you lose the possibility to experiment with harmony and reharmonizations.

Biab, Kontakt, Sampletank and lots of nice libraries, from Fluffy audio to Abbey Road drums.
