"as to various daws on the market lets not forget they dont have
the complication technically of offering the track generation features of bb and rb."
There are VSTis that do this like NI Session Guitars, UJAM Guitars Piano Bass, MusicLabs Gutars, Toontracks EZDrummer Bass Keys.
Then you now have Logic with Chord Track and AI instruments. Not to mention you now have a RealTrack keyboard. You also have JJazzLab that has millions of styles and works as a Live Arranger.

"Lets not forget that they have their own complexities. They are addressing them. So as PGM, but at much, much slower pace. Hopefully this time around it will be different.

Hopefully this time around it will be different if they are using a new crossplatform code designed for audio applications to resemble the quality of Song Master Pro.
