"Hardwire Mod by A.S.M.O.

asmo23.wordpress.com


This is a hardwire mod of the Dirty Carter Experimental Sound Generating Instrument, a post card sized hand held touch controlled instrument, designed by John Richards (Dirty Electronics) and Chris Carter ( Throbbing Gristle, Carter Tutti). It was originally produced for a special performance by Carter and the 25 strong Dirty Electronics Ensemble in 2010. Chris’ artwork is etched into the PCB and forms part of the circuit.

The instrument is mounted on a custom built wooden case with aluminium face plate is covered with black leatherette.

On this mod all the touch points are wired up to pots, with rotary switches to select clock range and feedback input, giving more precise control and predictability. The mix tilt switch is disabled and rerouted to a toggle switch. The original speaker is removed and a ¼ audio out socket added. Also added is a low pass filter with resonance and cutoff controls with an LFO for modulation and CV in. At full resonance the filter self oscillates.

The original instrument and additional circuitry are powered from a 9v PP3 battery

The 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. Sound from both the 4-stage shift registers can be mixed together. Glitchy noise, deep drones and percussive peeps!"

"The Dirty Carter Electronic Sound Generating Instrument was designed by John Richards (Dirty Electronics) and Chris Carter from legendary Industrial pioneers Throbbing Gristle. It was produced for a special performance by Carter and the 25 strong Dirty Electronics Ensemble in 2010. It was originally designed as a touch controlled instrument with the player's skin resistance completing the circuit. This hard wired modification by A.S.M.O. gives more control and predictability by wiring all to the touch contacts to pots and switches. An additional low pass resonant filter has been added, LFO and an external CV socket for filter modulation. The case is made of stained ply and the front panel is covered with black leatherette."

This instrument was designed in collaboration with Chris Carter from Throbbing Gristle for two specific events in Leicester, UK and Amsterdam in 2010. A few of the printed circuit boards were left and have recently been assembled by ASMO. Limited editions of 10 instruments now sold out. This unit has been used for half an hour so is in perfect condition. Collector's item.

Features
--------

Digital noise, Feedback, Wavetable synthesis Self-supporting/hand-held device, Tilt and touch controls.
