EZMIX - 4-channel CV/Audio mixer

A little easy-to-make and simple mixer for audio or CV mixing. Has 4 inputs and one output. It sums 4 signals and inverts them keeping the amplitude the same, and then inverts it once again. Very stable and nice!

EZMIX does not have input DC coupling (means: no input capacitor which will block DC from passing with audio). It is done purposely so that it can process both CV and sounds. Some sounds can starts clip and interfere without DC coupling if too loud, though, so be sure to adjust your volumes correctly! (unless you want the audio to become a hell mess, which is nice, too)
