I decided to learn how to play bass (already play e guitar). I have BIAB UltraPak+ , so wondering what would be the best way to use this program to learn bass. Obviously I can pull up any chord progression and style and mute the bass part to play along...so there is that, but I am also wondering what are the best resources in this software package for learning bass lines and grooves (which I can then later mute the track and play myself)

I see there only a couple of instrument studies for bass. That's a start, but there are only a couple. Generated bass style bass parts tend to be kind of simplistic, but obviously I could just look at the notation for those and attempt to learn to play those...

Are there any other good sources of good bass playing in the band in the box universe and what would be the best way to go about learning bass (in addition to being able to mute the bass part and experiment play along).
