The mixer is there purely to give some control over the level of each VCO. It doesn’t need any thing special such as tone controls, send and return channels etc. It’s just serving one basic purpose. You could use Level Adj modules, but I prefer the more natural control the VCA gives over the linear adjustment provided by the Level Adj. I have included the Peak Meter so that there’s a visual indication if we are getting close to clipping levels at the output. Quite important if we are mixing the signals from four VCOs, as when the signals are in phase the levels will add, and can get quite high.
You could add a master level control at the output using another VCA, but it seems a little superfluous to me (all down to a matter of personal preference).
The link “module” is just a container used with the input and outputs directly linked to allow connection of the Peak meter to all the VCA outputs
