This is beautiful. Do you control the oscillators on/off or controll them by volume?

Fascinating. And just a tiny bit bonkers! :)

Amazing work. Very refreshing. In this world of electronic dance is nice to hear something original. Excellent microtonal piece

it's like unholy digital bagpiping.  cool as fuck too.

Ode To A MetalBox

This is the first track to be credited to my latest alias, Occam's Raygun, the alter ego I plan to use for strictly modular synth work. This piece showcases the Moog Mavis module for both the drum and melody line patches.

Mesmo “Absence and Presence”
Text: James Joyce

Voices:
Leopold Bloom – Ronnie Walsh
Stephen Dedalus – Patrick Dawson

The works Inflowoc, Accraol, Janesem, Rivlinone, Mergerime and Pippinur employ samples from the James Joyce “Ulysses” broadcast which occurred on Bloomsday 1982 when the Irish state broadcaster, RTÉ Radio, transmitted an uninterrupted 30-hour dramatized radio performance, by 33 actors of the RTÉ Players, of the entire text of James Joyce's epic 1922 novel, “Ulysses”, to commemorate the centenary of the author's birth (born 2 February 1882).

Stormy Memories (NaviarHaiku 545)

Micoilalacora

T-60-120

Laptop running Pd, which is using csoundapi~ to execute a Csound instrument. This is controlled by an Arduino (the wooden box with the knobs and switches, which was made for me by Doug Seidel). The output is going through a reverb unit and then into an amp. Recorded live then normalized and minimally edited (fade-in at the beginning), no EQ or other processing.

The Csound instrument I'm playing is something I call the Difference Engine. Given a frequency and a frequency ratio, it generates eight oscillator tones: the input frequency, the ratio applied to the input frequency, and a series of difference and summation tones based on those two tones. There are actually two different instances of this, one controlled by the top three knobs and the other controlled by the bottom three knobs. For each set of three knobs, one sets the initial frequency and the other two set the numerator and denominator of the ratio.

So this is in essence a drone box based on an application of just intonation plus acoustic principles. The occasional glitchiness (which I dig) comes from tiny variations in the Arduino analog outputs. The sample/hold-type stuff happens when I change the ratio values rapidly.

From Complex Silence 12, released February 2011. Full release at <a href="http://www.archive.org/details/Complex_Silence_12" rel="nofollow" target="_blank">http://www.archive.org/details/Complex_Silence_12</a>.
Binaurally-beating sine waves in just intonation. Made with Csound and blue.
Best listened with headphones and eyes closed. Dedicated to Eleh.



Gyre II (from "Complex Silence 12", 2011)

A single chord tuned in just intonation, with each note's spectrum stretched using exponential curves to an interval of 21/20 (a "septimal chromatic semitone") and back again. The chord consist of the intervals 9/8 3/2 1/1 4/3 7/4 (in that order, low to high), where 1/1 is 240 Hz. I used a waveform made from the first 11 prime overtones. Some reverb was also applied. Made entirely in Csound with blue, converted from 96/24 WAV to 320kbps MP3 in Audacity.

Drift Study III

From Complex Silence 4, released October 2009 on the Time Theory netlabel. It uses scales based on the golden ratio, and was made with Csound, blue, and Scala. The full release is available at http://www.archive.org/details/tmth06A. Cover image by Phillip Wilkerson.

Meridian Transit (from "Complex Silence 4", 2009)

Mark (aka Mystahr) at the Justnotnormal Netlabel has just released their second massive compilation, no-R-mal II, 71 tracks of experimental music organized into six sets (each of which is suitable for burning to a CD). Each CD has a theme; the first one is called Warm voices, and it includes a track of mine called Penumbral.

Penumbral started life several years ago as a piece called Passacagla & Fugue State and uses a “scale” I built from the set of pitches used in the La Monte Young sine wave installation called (deep breath) “The Base 9:7:4 Symmetry in Prime Time When Centered above and below The Lowest Term Primes in The Range 288 to 224 with The Addition of 279 and 261 in Which The Half of The Symmetric Division Mapped above and Including 288 Consists of The Powers of 2 Multiplied by The Primes within The Ranges of 144 to 128, 72 to 64 and 36 to 32 Which Are Symmetrical to Those Primes in Lowest Terms in The Half of The Symmetric Division Mapped below and Including 224 within The Ranges 126 to 112, 63 to 56 and 31.5 to 28 with The Addition of 119”. This is a revision of my earlier piece, with (hopefully) higher-quality sound and several other changes here and there.

The piece was not intended to imitate natural sounds, but it did result in some sounds that are somewhat reminiscent of the peepers and insects that can be heard in rural places. Listening to it this morning, it blended very well with the cricket sounds coming through the open windows of my living room.

Here is the track for streaming and/or downloading, but I encourage you to check out the rest of the No-R-mal II release — there’s a LOT of good music there.

Penumbral (from "no-R-mal II", 2010)

From January 2006, the title track of my first CD-R (Glass Museum) and netlabel (NetNewMusic) release. Original notes: http://mysterybear.net/article/14/sublimation. Netlabel release: http://www.archive.org/details/nnm007

Now available at http://mysterybear.bandcamp.com/album/sublimation in FLAC (lossless) format.

Sublimation (from "Sublimation", 2008)

Experimental electronic music, mostly in the drone category. This is where I put live sets, one-offs, experiments, and excerpts from longer releases.

CD: "~60 Hz" on Irritable Hedgehog - http://recordings.irritablehedgehog.com/album/dave-seidel-60-hz
