This interface was developed for SkNote for their hardware Theremins. A theremin is a musical instrument that works by emiting a continous tone/pitch and modulating the volume and pitch with two separate antennas. As the musician moves their hands toward and away from the antenna, the signal is modulated. You probably have heard a theremin and didn't realize it -- it was very popular for music and sound effects in the old black and white science fiction movies of long ago.
