I just got done making some backgrounds for use with the etudes in Walt Weiskopf’s book Around the Horn.
The backgrounds were generated with Band in a Box 10 and tweaked with Digital Performer 3, and recorded using my Alesis NanoPiano and Roland Sound Canvas.Bb Backgrounds
The number after the name is the metronome marking the song was recorded at.
Update: I removed the original links from 2001 a long time ago. I have now just put up the Band in a Box files for people interested in them. Enjoy!
