YouTube via matrixsynth "James Husted of SYNTHWERKS goes over the FSR-4 and MG-1 modules at the New Wave Modular Synthesizer PNW AES Meeting at MS Studios."
Note the FSR-4 is pressure sensitive, not capacitive, so it actually reacts to physical pressure. The circles you see in the image below each column of knobs is a membrane resting on the surface of the metal faceplate. You do not need to make skin contact with them like other faceplate controllers. You can use sticks to trigger them, or if you happen to be wearing gloves, they will still work.
