My latest album “Passion for Numbers” is released today! You can stream it for free on Bandcamp: https://shop.mentalgroove.ch/album/passion-for-numbers The video models the phase relationships of the first six prime numbers, synchronized to an excerpt of “Ibaramu” (track 5), which is simultaneously in 1, 2, 3, 5, 7, and 11. Ibaramu means “harmonious” in the Yoruba language.

$Plasmagon Plasmagon is an algorithmic choral piece. Its entirely a capella and has an ambient, environmental mood. Plasmagon was performed by eight samplers, controlled by custom software. It would be practically impossible for humans to perform it, due to its dynamic and rhythmic complexity. Plasmagon has three unusual qualities: it doesnt have edges, it modulates stealthily, and it times modulations by listening to itself. No edges means no sharp attacks or decays, i.e. all sounds fade in and out gradually, yielding continuous harmonic gradation instead of easily distinguishable chords. Stealth modulation means that the key only changes by one note at a time, and only when that note isnt in use by any of the voices. The listener is a type of sensory feedback that monitors the output and detects optimal conditions for a modulation. Plasmagon is generated by a combination of rules and polymeter. The polymeter consists of loops of differing lengths shifting phase relative to one another. Plasmagon uses fractional polymeter, i.e. the loop lengths arent integer multiples of a common meter as is usually the case. For this reason in particular Plasmagons phase-space (the range of variations before repetition occurs) is very large. Plasmagon was originally developed as a musical accompaniment for the authors geometric visualizer, Whorld (see whorld.org). In the original installation, the same polymeter loops that control the choral voices also control Whorlds parameters, resulting in true synesthesia, i.e. the viewer sees the music and/or hears the visuals. The progression is a cycle of neighboring keys, as follows: E major / A major / D major / E melodic minor E major / B major / F# major / F# melodic minor Timing of the first cycle (approximate): 00:00 E 01:30 A 02:20 D 05:20 Emin 08:00 E 09:40 B 10:30 F# 12:40 F#min 14:40 E Created in 2009 Note that the original Whorld visualization suffers from compression artifacts, so in this video it was replaced by a different visualization, created using a different open source software (also by Chris Korda) called Triplight (available at Github and Sourceforge).$

$Fractice Mandelbrot deep zoom to 2^316 (bigger than the universe!) This is an extremely deep dive into the Mandelbrot set, to 2^316 (binary). In decimal thats 1E+95, or 1 with 95 zeros after it. The coordinates are identical to a similar deep zoom movie posted to YouTube by user metafis, but my version has higher resolution (648x480), and was rendered with 2x antialiasing (four pixels computed for every output pixel). It also has an improved palette, similar to the one used by the Wikipedia Mandelbrot page. The uncompressed video looks better of course fractals are close to the worst case for video compression but H.264 does surprisingly well. The video was rendered using my own fractal software, called Fractice, which supports distributed processing using a client/server architecture. The render took five months, using a cluster of up to 20 dual-core PCs on a LAN, all running the Fractice rendering server. The actual number of servers varied over the five-month period but averaged around 15. Rendering only occurred at night. Fractice is a free, open-source fractal explorer/renderer for XP/Vista. It supports navigation, history thumbnails, previews, antialiasing, deep zoom, printing, posters, palettes, multicore and distributed processing, movie recording, undo/redo, color cycling, and job control. It also has VJ features, such as mixing, mirroring, origin motion, palette tweening, dual-monitor, and MIDI. For more info and to download Fractice: http://fractice.sourceforge.net$

$Al Fasawz Al Fasawz is a 38-minute ambient soundscape inspired by the sound of waves on the beach in Rockport, MA. The track is algorithmic music, and is intended for relaxation and meditation. It was created from a fixed number of sawtooth waves of constant pitch and stereo position. The waves are continuously frequency modulated by control loops of varying lengths, resulting in complex fractional polymeter which gives an impression of self-similar but non-repeating structure. The loops were controlled via custom software written by the artist. As in the later work Plasmagon, the algorithm includes feedback: a listener that monitors the output in order to determine the optimal time for changes. In this case this listener decides when to trigger the bass samples, based on its estimate of overall intensity.$
