I didn't try the setup he listed. It looks valid, enviroment is a bit overwhelming, most people shy away for it. BIAB is a great tool, but the Mac version is way behind the PC version. In fact I have found the Mac version of BIAB to be fairly buggy, but does an amazing job of helping you to quickly get a song into a 'shape'. I never got the BIAB copy into paste buffer to work. I did a simple work around
I just create a Logic setup with the instruments, in the same order as BIAB saves them.
In BIAB do "export as midi". then open up Logic, and drag that midi file onto the arrange page. It plays fine. I will often create several versions of the song in BIAB, using different styles, then in Logic, I will use different sections of one instrument, with different styles, the piano maybe a jazz style, the bass a hiphop style, guitar, a folk etc.
It is a wonderful way to get the skeleton of a song going. You can BIAB to finetune the chord progression, try a transpose etc, I will then go back in, and mute the BIAB bass for example, and play my own
