Default Q: Is the Track Pan envelope inverted?

Is the Track Pan envelope inverted?

Here is a track with three envelopes, all with the same envelope curve:
(a) track volume,
(b) track pan,
(c) VSTi parameter in Kontakt - instrument pan.



You will see that the track Pan value is 55% left and the Kontakt Pan Value is 56 Right and the slider handles are in different places for the same envelope point. The sound was panned slightly into the right monitor (as can be seen in the big meters on track 2 (a Receive from track 1).

I would have thought that the track slider should follow the envelope value: as the envelope increases the slider handle goes to the right - that is, the mirror-opposite of how it is currently moving.

And the audio would be panned to the right - the opposite of what currently happens. :shock:

AFAIK, It's up to Kontakt how it interprets the "pan" setting. In other words, from Reaper's perspective, the Kontakt "pan" isn't a "pan", it's just a VST parameter that Kontakt has defined in a certain way, and it happens that apparently Kontakt and Reaper see the pan in opposite polarities.

To me, it makes more sense that positive pan values would go to the left, but it's arbitrary.

What you're doing there is telling kontakt to pan 55% right, which it does (as shown in Kontakt's meters). Then it outputs to the track leaning to the right, and reaper changes the balance 55% back to the left, resulting in the slightly-right result (due to whatever nuances of the pan calculation.)

Perhaps you were just demoing the difference, but just in case: of course you likely only want one of those pans in effect: just use whichever works better for you.
