MMI Touch and Pressure Controller 4HP - Herzlich

The Man-Machine Interface, or MMI, is a passive touch and pressure sensitive controller which allows the user to direct CV and audio signals at will.

The MMI consists of three input/output jacks, and five body contact surfaces in glorious gold.

The zig-zag body contacts correspond to the input/output jacks, with the top zig-zag connecting to the top jack, the middle zig-zag connecting to the middle jack, and the lower zig-zag connecting to the lower jack. 

The spiral patterns in between the zig-zags are comprised of the two adjacent jacks, so the upper spiral is comprised of the upper and middle jack, while the lower spiral is comprised of the middle and lower jack.
