Welcome Bob z,

I teach guitar and BiaB is my partner, both for my students and for myself. I make backing tracks for my students to practice with. I also do the same for myself; I like experimenting with styles I would never have used myself before BiaB. If you use midi backing tracks, note they will not sound as good as RealTracks if you are using an inexpensive GM sound source, you can very easily speed up or down the tempo without changing the pitch.

I agree with Kevin on all of his thoughts.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
