I'm on a Mac and I'm considering BiaB but not sure it's still a quality product. The interface looks pretty dated and the intro video says "Johnny Highland" about every ten seconds. Has its day come and gone and you might as well use backing tracks you find on YouTube? Or is Band in a Box still a worthwhile product today? My usage would be to practice walking jazz and blues. The biggest drawback is that today I can pull out the bass on the original recording in Moises for like $4 / month.
