I'm trying to figure out how to pan a stereo signal.
Most of the examples in the manual/tutorials, included examples and
3rd party objects
take a mono signal, then create a virtual stereo image and pan.
what i'm trying to do is take a stereo input and pan the stereo signal.
i know i need to use two separate constant power pans (one for each
signal...i'm thinking of using nathan wolek's cppan~) so that at the
center position, L would be 0 and R would be 1; at hard right, L
would be 1 and R would be 1 and at hard left, L would be 0 and R
would be 0. I want to use a master slider to control the values of
both cppan~ objects. What I'm having problems figuring out is, as
you pan from hard right to hard left, the L value would decrease 0 to
1 and the R value would stay at 1, as the master slider reaches
center position. As the master slider passes from center in the the
left side, however, the R value would move from 1 to 0 while the L
would stay at 0. I guess what I can't figure out is how to use a
master slider to control both values, but scaled in such a way as I
described. (The biggest problem I'm having is how to have the L
value be at 0 and the R value at 1 when the main slider is at center
position.) Can anyone help me figure this out?
Thanks for your help!
P.S. I am aware of the discussion below, but can't figure out how to
implement what lawrence describes, using the split object.

this sounds to me like twoconstant power pans, one for each signal. For
the first half of the pan you are panning the right input from left to
right outlut; for the second half you are panning the left input from
left to right output. Use the 'split' object to divide your control
into two halves.
