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 synthesisers..
It comprises a four channel polarising 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, converting a bipolar +/- 5V modulation into a unipolar 0 to +5V
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!
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 CV’s too. All of the inputs are bipolar, which means that either non-inverted or inverted version of the input signal can be added to the mix depending upon the Input control being turned clockwise (non-inverting) or anti-clockwise (inverted). The 12’o’clock position is zero.
