The MiniMod CVMix-Offset-VCA is a compact 10hp wide Eurorack format module. It has been developed to offer a range of useful utilities for the MiniMod system and, of course, other Eurorack synthesizers.

It includes a four-channel polarizing mixer, amplifier, inverter, a voltage source, and a DC-coupled VCA with switchable CV offset.

Uses include mixing together CV modulation sources, mixing an offset voltage with a CV source, and converting a bipolar +/- 5V modulation into a unipolar 0 to +5V signal.

This is possibly the most useful utility module that can be added to a modular system—you'll wonder how you ever managed without it!

In Depth

This useful module is a Bipolar Mixer, DC voltage source, and Linear DC-coupled VCA. With no input to channel 1, the Input 1 pot becomes a voltage source with a range of +/- 6V. The control pot and input for channel 4 can be switched to become an offset control and/or a second CV input for the VCA. Input 3 has 2x gain, so it can amplify lower-level CVs too. All of the inputs are bipolar, which means that either the non-inverted or inverted version of the input signal can be added to the mix depending on the Input control being turned clockwise (non-inverting) or counterclockwise (inverted). The 12 o’clock position is zero.
