theduke530,

I don't use Music Maker but your problem is similar to those experienced by user of Magix video editing programs so I'll try, given the very little detail you have provided...

Assuming you have your beat is on one track and your vocals on another, the video program solution would be to simply move  the vocals (I'd assume a .wav file?) a bit by clicking and dragging along the timeline so that the beginnings line up. That may be all you need to do, but if things still get gradually out of sync as time goes on you will need to 'stretch' the audio track so that the ends match. This changes the play time without changing the pitch. Magix video editors have this option and I'd assume that their music program would do the same.

Regards,

Carl
