Toucher,

The Roland Sonic Cell looks like an awesome piece of gear. It will make Biab sound like a whole new band and program. You won't be limited to just the Real Tracks for making music with that sounds authentic. Some of the best styles in Biab are midi and they need a good sound source to do them justice. The soft synth route doesn't cut it for my taste.

Check with your local music dealers and see if they might have one in stock to demo. Try before I buy has always been my motto when looking for new gear.

I think the Sonic Cell also touts a vocal harmony feature, if I remember correctly?
