I haven't researched this yet but let me say this.My setup has all the music panned hard left and just 1/4 note root position piano chords panned hard right to drive my vocal harmoniser.I just batched processed all 200 of my songs so I can load them into my MP3 player. They all processed as stereo with the hard pans still intact.
You'd be amazed at the issues that are solved by returning to factory settings.I do it each session with a little tool I built.
