The Dirty Carter E.S.G.I.

Pictured here fresh off the workbench is The Dirty Carter Experimental Sound Generating Instrument, designed by Chris Carter from legendary industrial pioneers Throbbing Gristle and Dr Noise  John Richards. The instrument has been designed for a special performance by Carter and the 25 strong Dirty Electronics Ensemble ( of which I am a member ) which will take place at Phoenix Square in Leicester on 28th April 2010.

We built the instruments during a workshop last week and we rehearse tonight and tomorrow for the gig on Wednesday, click the Phoenix Square link above for tickets.

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. A second tilt switch engages the low pass filter. It is the size of a postcard and the art work designed by Chris is etched into the copper on the front panel.
