Hi,
Unfortunately that is not what this program is for. You can create your own instrumental versions but removing vocal is difficult and sometimes impossible.
You need to search for a .vst plug-in that will do this, they are called vocal remover or karaoke plug-ins. These will only work if the vocals were recorded straight up the middle of the stereo field without effects. Sometimes you can remove vocals but there will be artifacts left behind; other times you will not be able to remove them at all.
Once a song is mixed down into a single unit it's nearly impossible to remove any one part. It's like baking a cake and then trying to remove the eggs.
I agree wit hno turning. Usally a lot of vocal removing is done by removing the vocal range in an equalizer - often with the result, that you can hear the song in the background or otherwise.
You could also try to find a midi-version of the song > import it into your program and use the programs sounds and instruments to recreate the song.
But removing the song from the original score is very difficult, not to say sometimes illegal - depending on your use.
