All very interesting stuff, thanks! I didn't need anything too special so i've adapted Hans' equal-power pan (I've turned it upside down to make a crossfader). I only needed it for the ring modulator patch i've just posted on my blog (http://guitarextended.wordpress.com/2012/02/06/ring-modulator-effect-using-pure-data/)

Cheers!

Yeah, I confused that right from the start ... missing-coffee-excuse ...

This has its roots indeed in the use of fading identical signal(s). If you use
different input sounds, the CP-fade gives nicer results. Attached is an example
that uses the linear/cp crossfades from the rj-library as subpatches and fades
two different signals and then the same signal twice.
