Subdivision of lines to simulate mountain horizon. MIDI channels 1-8 in the TX816 and Proteii are tuned in intervals of 12.5 cents by freezing the pitch bend wheel for each module at the beginning of the piece. The numbers on the vertical axis of the graph are scaled to a range of six octaves and then rounded to the nearest eighth of a semitone. The whole number part determines what MIDI key will be pressed and the fractional part determines which of the eight channels will receive the note. In music they produce a sense of tension and release that is appealing physically as well as esthetically.
Phrases begin with most notes in a single channel.
As the phrase progresses, the notes fan out among the eight channels and the richness of the micro tonal palette is revealed. Near the end of each phrase the notes move toward a different channel and cadence in relative consonance. The center of gravity is constantly changing. Like the tuning system, the timbres are designed with a rich inner life. Voices vibrate and beat against other voices.
