peteralias,
Let me say that firstly if you are looking for perfect vocal removal, this cannot be achieved by any software. Multitrack recordings that are mixed down to left or right channels or center panned or any combination therein will not be a real good quality sound after vocal removal. Some are pretty good but the key is if the vocals were recorded dead center pan. If they were you can get a pretty good end result but again, not without some loss of music quality.
I have tried removing vocals on about 25 or 30 songs and only ended up with about 7 that are good enough quality that I am actually using. It's the nature of the beast.
Hope this explains a little,
Wally
