basically convert your music to mono, but i don't know how to do that in soundforge. there must be a setting you can change and save your song that way. i have had that happen before and it's because one of the channels in the sound system isn't working, either right or left. drives me crazy because if you have a show and hire a pro sound person, there should not be such amateur problems. but it happens way too often so i'm thinking about converting my stuff too even though i love the stereo stuff. good luck!
