Question

Hi,
I have been using studio one 3 artist for a while and haven't had any problems. But when i booted the program today something was wrong. I recorded the vocals on one track, and had a beat on another, like i always do. But when i pressed play afterwards it was totally off beat. it looks like the tracks match when looking at the sound wave, but when playing the song it's totally off.
I've already reinstalled the program, rebooted the computer, everything. No improvement

Answer 1

Maybe one track is being timestretched by tempo and the other one isn't, but should be.

Look at the timestretch field in the Inspector.   Also look at the clip Inspector there and make sure both files have a base tempo reference.
