At times BIAB can be a frustrating tool.
The UI is complex, aged.
Sometimes it crashes for no good reason
Its a project over 3 decades old.
But mostly it works. Eventually you figure out a workflow that is good enough.

Important to remember- BIAB does NOT come with a "read my mind" switch.
It has no idea what you specifically want. Basically It knows what neighborhood you want to be in

For example , If you want to create an arrangement of a song in a certain key, at a certain bpm, in a certain style, its hard to beat.
There are some things you can tweak to change it, but you can't yell at the bass player and tell him to do specifically X at bar y without using midi or recording the line you want yourself.

For me its great.
I can machinate the output of a BIAB arrangement in my DAW a little bit and end up with pro level backing track.
Say Its a swing tune, It sounds just like swing AND Ron Carter's on the bass.. Thats a good enough groove for my level of playing.

For some of us, that's the wrench that BIAB is... A tool. Pretty damn good little combo if if you ask me.
THey show up on time, they play in tune, the drummer doesn't hit on your girlfriend. What's not to like.

For others that's not enough. They want to reproduce EXACTLY some part or arrangement.
Sometimes that does happen, but mostly not.

For that you need either midi or a bunch of musicians (or yourself who can play all the parts).

Anyway, OMIO.

Good Luck
