I couldn't open your link but I found a youtube video that addressed that, it may be the same one. So yes that's what I need. I went throuhg and followed the steps to mute a track at the start of chorus 2 and bring it back at the start of chorus 3 then saved the song. But it didn't save the volume adjustments. I looked for an "apply" or "ok" button but couldn't find one. I'm feeling pretty dumb but how do I save the changes I made to the chorus?
