Not following what your question really is.
The outputs are stereo, so the sounds intended to go left go out the left output jack, same concept for the right. Voices in a program are assignable on the output page and can be placed anywhere in the stereo field, i.e. hard left, hard right, 72% left, 28% right, etc.. Negative value assignments pan the voice towards the left, positive value assignments pan the voice to the right. This assignment is for each individual voice within the program, so if you have a brass program with sax, trumpet, trombone, each one of those can be panned differently.
Is this the answer to your question?
