Help me out here, cause I've been using that particular dirty-but-

channel and the inverse of that to the right channel.
Never mind! I figured it out. There's one patch cable in the
wrong
place in my version. If that were fixed, our maths would be the same.
Yes, it's the same. My version might be slightly faster because it
avoids a multiplication, but then it has a variable replacement in a
message box, which also is a bit costly. Normally I use something like
[expr 1-$f1; $f1]
to do the splitting in one object but I once heard that you don't like
[expr]. (Just joking ;)
Using [expr] for panning has the advantage to allow for writing
alternative pannings in a very compact way like:
[expr sqrt(1-$f1); sqrt($f1)]
[expr cos(1.57 * $f1); sin(1.57 * $f1)]
Attached patch shows them all.
I put these three panning algorithms into objects in the pan
library, and added another odd one devised by a guy named gogins, and
included a GOP panner.
They are in the pan library in Pd-extended, or in CVS:
