Urs,
I was checking out the pan laws for Z2 and FSVA. I noticed a few things that surprised me and was wondering why you chose what you did.
First Z2. When I pan an OSC or a Comb, it looks like you're using a -3.0dB rule. This is different if I manipulate the Pan knob for a specific voice mix it looks to be a -6.0dB rule.
When I loaded up FSVA and tried the same thing with the gloabal Pan knob, it's a -3.0dB rule.
Just wondering why you chose the different laws for each area.
Pan-laws in u-he software?

Hiya,
Most panners are naturally -3dB, and most panners pan mono sources*.
The voice mixer of course gets a stereo signal. In that case it's by default using stereo balance rather than "true" panning, in order to save lots of cpu cycles (otherwise the mixer would probably be as much as a decent filter module). When you pan hard left, it does not contain any signal from the right side anymore. A mono signal should still be -3dB, but I don't exactly know about unrelated signals...
What about setting a channel to "Pan" rather than "Bal"? That should pretty much keep 3dB, regardless if mono or stereo input... it's just a bit more expensive on cpu...
Btw. I'm using square root rather than cos/sin.
Cheers,
Urs
*everything that has a "width" parameter, like oscs, consists of multiple mono sources

Thanks for the usual quick reply Urs! I have been playing with panning modulation in some patches and noticed a few sound dips (the 6db pan). Switching to bal as you said fixes it nicely. Yet another thing I have to remember to add to the "all things u-he" wiki when it opens to the public.
