Network Extended Moog
A one-hour improvisation that was webcast from my home studio and relayed to an online audience via an event curated by John Bowers.
Visually the work focuses upon the repetition of a single one-minute video loop. The loop is not perfect and therefore skips rhythmically at approximately one minute. The source video loop was recorded from a networked CCTV camera, using a process known as ‘Google-hacking ’. The loop was then repeated sixty times and sound-tracked by an improvised work for the Moog Little Phatty synthesiser.
A single tone drone is built up form the Moog, in this instance of the piece a D tuned via two oscillators (sinewave modulated by squarewave). The note is sculpted within the Moog by envelope shaping; eliminating the attack and decay to leave a sustained tone. The note is filtered internally by using tiny changes in frequency cut-off and resonance. In performance, the second oscillator could be detuned +/ - 4 hertz to create beat frequencies. A very low frequency oscillator could modulate the tone internally, within the Moog circuitry. These performance possibilities were used infrequently within the improvisation, any change to the tone generated internally in the Moog being as minimally as possible.
Instead, the drone is filtered, modulated, delayed and layered via four simultaneous webcasts that are routed back into the performance via a mixing desk, variable feedback loops, which are fed back into the mix, modulating the existing materials. In addition, three octaves of the same synthesised tone are used during the improvisation and were routed to different webcasts in Pure Data. This produced an evolving, complex long duration work that built vertically over an extended timeframe.
