Inspired by the ADDAC701 VCO waveform mixing section, the new VC Signal Router also updates ADDACs legacy X-Fade/Panner to a stereo configuration that also allows for 4 quadrant mixing.
Featuring two dedicated X-faders and a stereo VCA that can also be used as a third X-Fader. All controls have their own CV inputs and dedicated attenuverters for precise control.

4 quadrant mixing is achieved by using the stereo master as an X-fader between the left and right channels, this way you can plug 4 audio sources and sweep/crossfade between each and any of them using the 3 x-faders. Plug any 4 sources (4 waveforms of a VCO, 4 LFOs, 4 envelopes…) and sweep through, morph through or have them all mixed together.

For other configuration types Left and Right X-fader channels can be routed through the Master stereo VCA or sent directly to the outputs. A stereo direct input can also be routed through the Master VCA or sent straight to the outputs.

The Mono Sum output always mixes Left and Right outputs together allowing the possibility to use the module as a peculiar 6 channel mono mixer.

The VC Signal Router can be used for both Audio or CV Signals.
