I do it very much like guitarhacker(herb) explains.

I export the wav files selecting "one wav file per track" from biab.


I'm using Logic Pro X and have never had a problem adding the tracks to a project.
I like to copy the biab .wav's to the Logic project directory. Just my approach.
I can either select the file to add a track or drag and drop into the project

Theoretically I store the original wav file in the project folder till the point where my mods would make it useless to have as backup. In practice, they mostly lie around forever as digital detritus on my hard drive. Oh well, hard drives are cheap, even SSD's.

Good mixing.
