Pictor Alpha-Electroacoustic musc (2003)
Pictor Alpha unfolds in a process of theme and variations, as a repeating melodic and thythmic motive passes through transpositions, permutations, interjections, and timbral transformations. I generated the original source material in 2000 using PulsarGenerator, a sound synthesis program developed by Alberto de Campo and me. Using the original source matertial, I then edited each particle individually by hand. This involved rescaling the amplitude of each particle, adjuting it in time, possibly filtering it, positioning it in space, modulating it, modiying its phase, and so on. The pitched tones were formed by replicating individual particles at audio wavelengths. In this manner of working, the screen of the sound editor becomes like a painter's easel, holding the sound material in place.
