Question

My "Main" channel quit playing in stereo. After checking multiple cables, I'm sure the problem is in the program itself. Using Studio One 2.6.5 and Windows 8.1.

It worked great for years, so it's not a routing problem.

Answer 1

Things to try...

-  Check to make sure the mono button on the Master Bus isn't engaged.

-  Use a signal or test tone panned hard L/R and check your hardware outputs to see if the panning is reflected there.

-  If you have hardware that allows internal panning of the stereo output via a software mixer control panel, make sure the stereo outs are panned hard left and right.
