Hello bowlesj (et al),
I've been using BIAB live for the past 8 years for standards-based restaurant gigs in the Dallas area. BIAB in a Samsung laptop with Godin nylon string guitar, all feeding a small Mackie mixer and PA. Mostly Real-Tracks, it all sounds great.
I just click on the song I want and get a new build with about 5 choruses in about 5 seconds. Have never had any computer problems or glitches.
I'm far from "techno-shy" (EE by background), but when performing I prefer to concentrate more on the music than futzing with gear.
Just keeping things simple.
Good luck,
John Payne
