Herb,
Somebody might correct if I am wrong, but BIAB is programmed algorithms with some randomization happening.

You can throw rocks at me, but I find AI + music a bit disturbing. In a sense, why would one even want to go that route? Not enough music "out there"? I think what we have now (the common tools: BIAB, EZkeys, Chording apps, Synths & arps) are borderline between advance tools and cookie molds. In my view, one has to tinker with music because they have a passion to create something new, to reflect thoughts, mood, protest, learn, or something of that nature.

Obviously, there is nothing wrong with experimenting with anything, but I think one has to ask a question: Why I am doing this?
Sure there is/will be many uses for AI in music such as Meditation, time spending, relaxation, not to mention technicalities (like mixing assist) embellishing, jingles for commercials, elevator music and whole bag of other uses.

Personally, I would not want more than 5-10% of AI in stuff I am tinkering with. And even that is more for learning purposes and tech assist. It's like this... Would you go to art school to learn how to "paint by number"?
--------------------------------------------

I believe...instead of asking PGmusic to do AI stuff, it's better to leave it to what they do best. Record talented musicians and make RTs/RDs/Midis and examples of styles. As far as AI stuff and BIAB goes...VST3 (and future variants) will most likely support AI tech in deep ways and in my opinion the best approach would be for PGmusic to fully integrate with VST/VSTi technology and make the best use of it such as: Routing, drag and drop and other input, ergonomics, etc.

P.S. A short example. With relatively new Chord Track, now you can relatively easily integrate whole bunch of pattern/sequence/arp items in your BIAB workflow (VSTi) such as NI, EZkeys, Synthmaster and dozens more. It was confirmed that VST3 support is coming to BIAB in 2024.... Well in 2023, for most of us, early buyers.

The end.
