"...alternatives for my needs."

I just need a device to produce backing tracks for my practice. I like to play with real musicians when possible. I use iReal Pro, Jazz Play-Along by MTH, free on the Apple app store for IOS, and with $20.00 you can have all of the in-app add-ons which include 1300+ jazz standards and a be-bop collection. They have A.I. instrumentalists which I think sound great. I did use BIAB for acoustic sounds until recently.
