I read this first post but didn't go through all the others.

There is something called UserTracks for this reason. Look at the link, I got in contact with Chris and he was interested in creating commercial UserTracks and is currently working on them.
I'm sure if you contact artists they would be interested in creating UserTracks to post, I don't think you can expect PG to cater for everything.
The PG community needs to encourage this, I posted this around BUT there were only 2 replies to the link above.
You can contact session players and let them know.
There are tools like JJazzLab that will open UserTrack Templates SGUs and use any Yamaha keyboard style to play them.
This will let the session players open the UserTrack Template and save to Midi file, this will be dropped into their DAW, AND because I asked JJazzLab to export midi with midi chord marker names they will have the chords in their DAW and be able to record to the Yamaha Style !
Now, if you want to keep asking PG year in year out you can, BUT if you contribute to what I talked about things WILL happen, but how it is now no one out there knows about creating commercial UserTracks to sell to Biab customers the only way they will find out is if you email them.
Send them a link to JJazzLab and a link to PG Download UserTrack Templates halfway down page not the 1min ones they are useless,
Yamaha Styles download for JJazLab

When the session musicians post their UserTrack creation, if you support them it will support more UserTracks being made, more interest, maybe more people buying Biab & BBPlugin, more development put into UserTrack features by PG.
