Alkahest by Dave Seidel
A piece for the Implication Organ, using the non-octave Bohlen A12 scale. Recorded as a single performance on 21 October 2018. In retrospect, my primary inspirations here were probably Catherine Christer Hennix and Boris.
The Implication Organ is a drone-oriented microtonal electronic system, an organ that can play no more than two notes at once. Whenever two notes are played together, the IO generates chords based on the frequency ratio of these notes: combination (sum, difference, and product) tones, and intervals corresponding to Pythagorean and golden means. All sounds are produced by a Raspberry Pi 3 with Pisound running Csound, processed through a tabletop full of various analog and digital devices,including (in this particular incarnation): Pladask Elektrisk Matrise, 4MS/Repeater Noise Swash, DigiTech FreqOut, Zvex Fat Fuzz Factory, Red Panda Particle, Moog Cluster Flux, Earthquaker Avalanche Run, Strymon El Capistan, Pigtronix Infinity Looper, Boomerang III, Red Panda Context, and Ekdahl Moisturizer. It is played using a QuNexus keyboard and controlled by a Lemur OSC touch interface running on a Samsung tablet.
The Bohlen A12 scale is described at http://www.huygens-fokker.org/bpsite/otherscales.html.
