What you are thinking of is an entirely different product that produces CDG songs. Vogone is a simple program that takes an audio file and removes the center panned sounds.

To do what you want takes an audio workstation that can process the left and right channels separately. Usually the vocal track is added to one (Right I believe, but I may be wrong). Then, some players allow playing Left only (no vocals) Right only (vocals) bridged left to both left and right (sounds like stereo but it is left channel vocal-less only), or mix left and right.

Our Karaoke Pro workstation can prepare the audio tracks like this, if you have the master vocal track separate to mix into one channel. The professional karaoke companies using our Karaoke Pro can do this as they record the music and vocals separately.
