Thank you for the responses, particularly your comprehensive information Pinglis.

The track I am trying to remove the vocals on is a Frank Sinatra track which has been converted to MP3. It was just a fun project where i was trying to overdub my voice onto something with a big-band backing just to see how it sounded.

It seems that it is much more complicated than just using the supplied plug-in and rerecording the vocals. The actual band sound suffered as well so I don't think I'll pursue it.

thanks again for the info.

Cheers


Andy
