Program Note

Dualism was an important work in my life as it preceded my orchestral composition Legerdemain for orchestra and live electronics, which would exploit the technologies that I explored in detail in this work. In particular, I had developed a Max patch where the key velocity of the keyboard soloist’s performance on the Yamaha SY99 would control in real-time both the delay lengths of signals picked up by miked flutes and basses connected to a Yamaha SPX90 Multi Effects Processor, and the relationship between the coarse and fine frequencies of oscillators used within the algorithms of SY99 timbres. The net effect is a continually changing spatial environment, and a constantly mutating sonic palette from the SY99 that moves among harmonic and inharmonic spectra.
