Dirty Carter Experimental Sound Instrument

"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!

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.

A short video* of the new Dirty-Carter Experimental Sound Generating Instrument (E.S.G.I.) while putting it through its paces.

*My apologies for the thin sounding mono audio.

"the technological terror is a one-off, cmos-based, digital synth. there are nine patchable modules that include a number of single oscillators, a dual input oscillator, two synchronized oscillators, a 4-stage shift register (summed output), a resonant low-pass filter, simple arpeggiator, two external inputs (one for low level instruments [e.g. guitar, microphone, etc] and one for other square wave devices like atari punk consoles and photo-theremins), a 4-channel mixer, and a master ouput/volume.

this clip demonstrates the 4 of the 6 single oscillators, the dual input oscillator, the two sync'd oscillators, and the 4-channel mixer.

no external effects were used. output goes directly into a roland 15x cube practice amp."

"Here's what I did this year. Ok, I kinda cheated. I started last November, but due to delays I had the first module up and running in January.

Great big thanks to everyone who asked/answered questions and those who made these awesome projects available!

Module list: (left to right)

Bottom row:
PAIA midi2cv (never use it, think I'm gonna chuck it to make room for the appendage Cool ), MFOS VCLFO x2, MFOS dual VCA, MFOS VCO x2, MFOS noise cornucopia, CGS Psycho LFO, MFOS 24 db lowpass, MFOS multimode filter, Dual MFOS sample&hold, Dual MFOS ADSR, MFOS dual VCA.


Top row:
Wiard Wogglebug #3(with disturb mod)/Dual Buchla VC portamento, Dual Buchla 281/CGS analog logic, CGS Digital noise/pulse dividers/boolean logic/XOR XNOR/Analog shift register, CGS Gated comparator/burst generator, CGS VCO, Bridechamber BiNtIc/Tellun switching comparator, CGS suboscillator, Bridechamber wave multipliers/real ring modulator, Ian fritz 5 pulse waveshaper/Mankato filter, Fonik PS-3100 resonators/CGS cascade mixer, Tellun neural agonizer, dual CGS Tube VCA/Mixer.

P.S. In case anyone is wondering about the colored jacks, they are just the regular switchcraft type spraypainted

Red = Logic input
Orange = Logic output
Blue = CV attenuator input
Purple = Unattenuated(V/oct) control input
Pink = CV Output

Green = Audio input
