Focused versatility seems an oxymoron when describing the features that led us to design the Mixwitch. With only a pinch of mixing, inverting and controlled switching, we brew up a plethora of combinations and uses. This is voltage processing magic!
The Mixwitch design comes from a frustration with attenuvertors (bipolar attenuators-inverters) whose off (neutral) position is difficult to retrieve, especially in live situations.
We went for a digitally-controlled analog path where polarity inversion would be at the touch of a button. So, the usefulness of attenuating/inverting can be realized by turning the pot down, swiftly pressing the inversion button and reopening the level. The zero level is where you expect it, with the pot full down.
Once we had a clean polarity control, we easily added a mute function offering the benefit of pre- adjusted pot settings ready to be activated at will.
The next step was to bring something extra, useful and creative. There are plenty of analog switches controlled by a clock; but arbitrarily selecting an input with a voltage is less known. Having both control capabilities combined with our specific mixer features creates a unique fusion: welcome to the Mixwitch!
