A clean and uncompromising soundtrack that represents just modulation, no fx’s added. These 4 tracks are created solely by modifying the envelope of modulating frequencies, creating glimmering patterns. (sept2008)

2 tracks based on the principle of fm-synthesis. The timbre of sinewaves is disturbed by altering the envelope of the modulating frequency, resulting in complex and grainy soundtextures. The greek word piezein meaning "to press tight", is meant as a metaphor for squeezing the curve of soundwaves, which have been the case for these 2 tracks. (sept2007)

The basic idea for unison is the phenomenon of binaural tones. When the distance between congruence frequencies is changed, pulsations occur. Here, dutch artist christian toonk uses a self build instrument based on sinewave oscillators and feedback loops. The output is rewired to the input and provides a somewhat unpredictable datastream, by means of creating an opponent to interact to as in collaboration. Unison is an improvisation with sinewaves. although a technical approach, an emotive quality is pursued. (text: gerz) (nov2005)
