Mr. Grassi Module Stereo & Quad Mixer and amplitude modulated in realGrassi, a touch module, contains twelve square waves, used as the clock and data for shift registers, each followed by primitive resistor DAC. The DACs modulate clock and counter clock wise, yielding closed loops of perpetual modulation, triggered by touch. Each of the six outputs are a single, four bit DAC. Listening to them raw, they generate modem sounds to pure noise on touch. On release of touch, each DAC holds the contingent position of its
