I am attempting to separate the vocals from an existing song and make them stand out so I only hear them and no instraments. How do I do this? I've come close but It's still not 100% where I want it to be.
As you've discovered...you can't with MMM. It's not likely with any other software either. "Close" is as close as you're going to get in my opinion.
Go on you tube and search acapella and how to extract vocals...... It's not the easiest or cleanest but it might be the best option you have.... Good luck
Unfortunately, one of the better methods requires that you have the same track minus the vocals. How often is that going to happen?
Using the karaoke function won't cut it as it alters the frequencies of the track. That's assuming you have a karaoke feature that actually functions.
