Hello, first post here, totally new to BIAB, a little confused by it all so I need a little help with what version / packs etc I need to buy. Here's what I need to do:

I'm a jazz bassist, and I'd like realistic backing tracks for all the Real Book jazz standards for practice / studying. I currently either use iReal Pro (useful but gets very repetitive) or I program songs in Logic (I don't play keys so this can be very time consuming).

I'm looking for as close to a realistic sound as possible, and I only need drums, keys and guitar, but they need to sound good. The closer I can get to a real jazz sound the better - I don't need soloing or melodies etc, just convincing comping.

Thanks in advance.
