Hi, Does anybody know on an easy to use audio track canceling software for Windows XP? I want to be able to to take and CDA, WMA, or MP3 and cancel out Vocals, Lead Guitars and leave in just the Rythm Guitar, Bass and Drums and then eventually cancel out the drum tracks to play my own drumming in its place. I intend to use this as a tool for practicing my drumming. Any help will be greatly appreciated! Thanks.
