Didn't know how to name this topic...
I'll TRY to be clear. I want to position 3 sound sources in a stereo system, preferably headphones.
Let's say sound 1 is full left, 2 is center and 3 is full right
at a given time-position. If I move S1 a few degrees to the right,
I want either S2 or S3 to take the "space" left by S1. The result
should be a constant RMS. I want to automate the panning in a way that I'd only have to control 1 sound at a time to get the wright balance.
Panning algorithm could be circular or "local".
What I mean by "local" is: in the situation above,
S3 wouldn't be affected by moving S1.
Where should I start, any clue?

Maybe start with the rules
If (as in your example) S1 moved to the right, would you expect

S2 to move to the left and S3 remain still
or
S3 to move to the left and S2 remain still
or
should both S2 and S3 move to the left but by a smaller amount.

Would it be ok if all three ended up in the middle from time to time, or should there be a bias that some how reduces the chance of this happening.

Should it be that when one gets moved the other two try to move away from each other but maintain the equilibriam law.

It would better NOT to have all 3 at center position.
The idea behind this pannig is to keep counterpoints evident
for the listener. I want to keep it clear because the piece is
like a 3 parts invention in wich each part contains 3 parts...
and I want to put all chances on my side that the piece can be perceived as polyphonic rather than homophonic.

<<S2 to move to the left and S3 remain still
or
S3 to move to the left and S2 remain still>>

that would be my choice but I'm still trying to figure how to translate that into Kyma.
