I have two different edits of the same song. One version has a sax solo, the other a guitar solo. I want to put the guitar solo in to the object that has the sax solo so I'll have one song with both solos. I need to have the two versions play at the exact same time but one runs slightly slower than the other. I also want to cross fade the two tracks. I've been studying tutorials for 2 days now and can't quit put my finger on how to do it. I used the metrodome...but what grabs the two tracks and lines them up? Thank you.  p.s. I also tried the ditor and there only seems to be one track at a time with no option to layer tracks.
