but its better to stick wit originals 'cause you can get caught by the advisory stuff if you delete the vocals. although you want karaoke -non profit use. you can try youtube
So far, Karlito17 hasn't said anything that is of any use (or makes sense). And yes, you may be able to find and purchase a karaoke CD with the song(s) you want, but that was not the question. And yungthurm is incorrect....it IS possible with this software (MMM)...It's just not consistantly effective in all cases. I know because I've done it successfully myself. I can't post a sample because I used copyrighted material.
Like I said originally, you would use the Karaoke feature...that's what it's for. You'd rip the song(s) from the CD > Import the song into a new arrangement > Go to the Templates section and click and drag the Karaoke effect onto the imported material and let it process > Play the arrangement > If acceptable, export the track.
If you're lucky, it will do the job satisfactorily. However, the results are not always ideal, but sometime it is.
