As far as I know there is no software that will do what you want in 15-30 minutes. I know there are some out there selling some of that capability. My experience using some of it has been underwhelming. Interesting technology, but I'm not taking those tracks out on a gig.

I play instrumental tunes over backing tracks using a guitar, an ipad and a small pa. 95% of the tracks I created using BIAB and a DAW.

Truthfully, note for note is not for me.

I don't care much for purchased backing tracks or stems. I feel I can do better using biab in my workflow. I don't have much experience yet with midi, purchased or free.

BIAB affords you a lot of power to develop arrangements that fit you. Its not a perfect tool but it will help get you out and gigging with a solid "band" behind you. Assuming we get to gig again.

For me a new track simple 4 part track takes a good 4-5 hours to be ready for audition live at a club. Sometimes it takes a day, sometimes more. Lots of decisions need making. Your ideas don't always pan out first attempt. I suggest you start simple with easy song forms, changes and rhythms. Learn the tool a bit before you tackle something tough. After you make them, you have to practice them regularly. That adds to the workload.

Good Luck.
