“Skin conductivity, what’s your function? Hookin’ up modules like VCAs and gates.” These are the AllFlesh buttons, for use with modular synthesizers and other devices that accept the sort of control voltage that makes Eurorack equipment, such as pictured here, function. Usually one would patch a cable into one of those jacks from another device that would send it directions, but with AllFlesh the human body, specifically the finger, completes the circuit and thus any input jack can, in effect, become a button.
