Signal inversion in mixers when pan CV is used

[MarcBoule]

Bonjour Clément,

There seems to be a weird problem with the CF mixers (Stereo and Mono) when using the pan CV input as it seems like there is an inversion in one of the bus outputs. For example:

1. add a Mono module
2. connect a sine wave to its input at the bottom left of the module
3. send both bus outputs to both channel inputs in one VCV Scope
4. we see that both outputs are identical as expected
5. add a VCV 8Vert module and connect top output to the Pan CV input in Mono
6. set the 8Vert's knob to 50% (to produce 5V)
7. we now see that the bus outputs are inverted compared to each other (which introuduces unwanted phasing in the mixer)

The same problem is present in the Stereo module also. Cheers!

Marc
