CircuitMix

CircuitMix injects vintage console warmth into your DAW with analog-style summing, emulating the nonlinear behavior and subtle harmonics of vintage circuitry. Turn digital mixes into vibrant, organic and lively analog productions—with one click.

How to use: Simply insert CircuitMix on every channel. It is in no way a distortion plugin but applies very subtle harmonic content so don't expect to hear much on a single channel (unless you drive it super hard), but the effect will add up on your entire mix.

Knobs: Consider DRIVE your analog desk fader, 50% is unity gain, meaning the plugin circuitry outputs at the same gain level as the input that's driven into it. You can adjust this with the input and output gain trim knobs. Higher DRIVE amplifies the signal through the circuit emulation etc.
The TRANSFORMER knob lets you dial in a natural transformer coil behavior based on magnetic hysteresis, where at high levels the transformer chokes, narrowing the frequency output (less bass/highs). Use to taste.
