Throbbing Gristle’s Chris Carter puts a new audio device in his high tech arsenal through the paces:
The Dirty-Carter Experimental Sound Generating Instrument uses a dual 4-stage shift register. Each register is controlled independently. Two oscillators are used per register: one as a clock, the other as input data that is cascaded through the four stages. The outputs from the stages are mixed together. A fast clock rate produces a crude form of wavetable synthesis, whilst a slow clock rate creates audible pulses and clicks. The clock speed and the data input’s frequency are controlled by touch electrodes/pads. By tilting the instrument, sound from both the 4-stage shift registers can be mixed together. Glitchy noise, deep drones and percussive peeps!
