I'm kind of like justanoldmuso
'maybe' start in Biab, if not and I have a strong idea of what I want and plan to Generate just to fill in some stuff (which is way more likely around here) I just start right out in RB.

Generate what I need and time-sync other stuff.

If I'm just tinkering around, I'll try various chords/style combos in BiaB to try to find some kind of hint that inspires an idea. Same way I use any loop/generate/pattern software. BiaB is more efficient at that than RB.

But then once I have the idea I get out of BiaB so I get more control, even though it can be more work. I enjoy that kind of work way more than dealing with the leaves in the fall. <grin>

If I need something RB doesn't do I do not hesitate to move to Reaper, or others.

Mostly it's just figuring out the workflow that works best for you.

I cut my teeth on Roland software and Powertracks, so the workflow in RB is just familiar to me, & I work where I am comfortable until I have to move on.

Kind of like when I built houses. Get as much done on the ground as you can.
When you need to get on the roof, well, you move up to the roof.

I'm comfortable in PT/RB, but realize I sometimes need to get on the roof.
Not sure where BiaB fits into that scenario, maybe tinkering with floor plans before starting to build the house (?)

I do not work here, but the benefits are still awesome
