This project uses Ableton Live to create a live recording system for performing multiple saxophone tracks. Midi foot pedals control levels, starting and stopping of loops, and selecting tracks. I performed using this setup with two live drummers at festival gigs during the summer of 2010. Here is a video example from a sound check at Harry's Hoedown Festival in Somerset County, Maine - June 2010 with Shyam Brown on drums.
Here is a video from my studio which gives a better idea of how the multi-track layering works:
hardware setup
Behringer FCB1010 midi foot controller
Macbook
Motu 828mk3 audio midi interface
Roland keyboard amp
SM58 microphone
Both of the above examples use Latin Percussion loops from Ableton live.
