I was rummaging around an old hard drive and found a BIAB MIDI track made 22 years ago for my daughter to sing to for a high school audition video. I remember making it on the same day, and assigned a few samples I had at the time. She passed the audition with the video, and had been learning to sing jazz all during her childhood with a lot of thanks to BIAB to practice to, which helped her to become a successful commercial singer in life. We usually use RealTracks these days, but I forgot how good the old MIDI was in the early days.
