First off... welcome to the board.
To use in a live setting, I export from BIAB to a WAV file. Wouldn't want to rely on BIAB for live performance. I'm not familiar with the "looper pedal" or "mashine studio" so I can't comment on that.
I play my backing tracks directly from my laptop on stage. I use a PreSonus USB audio interface which sounds better than my laptop sound card and provides 1/4" outs to go into my live mixer. Using that setup, I don't have any problem with my tracks sounding "computer generated".
If you need more input, ask away.
Good luck.
Ditto. K.I.S.S. principle. Laptop with WAVs, backup files on Ipod.
