that's why you can freeze a track. BIAB has a mind of its own so when it gets it right freeze it. if you are working in BIAB all the way through and even with freezing you still don't like the bass choice of notes, live with the wrong notes until you're happy with the whole song, save and then open in RealBand and just do a multiriff for the short selection you want to change and pick the one you like.

i find RealBand easier to use for predictable results. of course it depends on whether the bass player played a five string bass on the original recording.
