I write and record music on a Boss BR 532 recorder. I like to use a lot of panning in my music. When I bounce the tracks to get ready to finish the song, it bounces into two tracks (making it a stereo recording instead of a mono one). When I transfer the files on my computer, however, it doesn't just transfer the song. It transfers each individual track. Normally this would be fine, but The final draft is in two tracks. How can I sync the final two tracks into one final song?
