My prediction, AI will help to re-write/translate at one point.
With 2024, most of my frustrations with BIAB are gone. Extremely fast track regeneration, Non modal MTP (Multipicker) Library where all content is available in one place, and other new items that help to compose more efficiently. My main wish for PGM is to fix most of known issues that are within the scope of reality handling real audio (RT's / RD's) and strongly consider a better UI and more intuitive menus.

thoughts on Modern music....

BIAB features hundreds of artists of wide specter of genres / cross genres. Instead of saying "gimme modern", I think a more productive approach would be to request something inline that was introduced in the past decades. For example, you find RT, RD, Style, etc. that you do like and request material similar to that. If you don't like any available material in BIAB, maybe you should start asking yourself uncomfortable question(s).

I do agree, that there should be a better genre balance, leaning center, and several genre/instruments that are very thinly represented.
I find useful, RT's/Midi recorded by Mike Durham, Sandy Williams, Miles Black, Jeff Lorber, Charlie Gannon (Peter, you need to convince your boy to do more!). Or something very particular, like a couple of baritone guitars by Brent Mason or Irish whistle by Geoffrey Kelly and many others. Personally I would like to have more of these type of tracks...
