A Postcard from Trappist 1 is an adaptive Just Intonation improvisation using the Parva synthesizer.

Micronation (Melodyne processed aeolian harp )

Saturday, March 11th, 2017



Micronation is an audio experiment where I took a ~30 seconds of aeolian harp captured during a high wind event and used Melodyne to determine each of four root notes by frequency. [The strings were tuned justly by ear but drift after several hours exposure to the elements outside, especially due to temperature changes] Then I used Paul’s Extreme Sound Stretch to isolation each vertical harmonic structure based upon the roots determined by Melodyne (10 harmonics high by 25 cents wide)and exporting the four files. Then I used Sonar to sequence the exported wav files and applied reverb, EQ, and tape simulation. The experimentally determined roots are 92 Hz, 118 Hz[59/46], 140 Hz[35/23], and 184 Hz [ 2/1 the octave of 92].

Loquebantur variis linguis in Adaptive JI normal and half speed

Wednesday, January 11th, 2017

The video is best viewed full screen. The half-speed version starts after a “note for nothing” to capture the reverb tail and a few seconds. The passing tones are very evident and dissonant in the half speed version. Loquebantur_variis_linguis PDF

turning of the sun inside out (Melodyne recomposition / acousmatic)

turning of the sun inside out is a recomposition of James Bailey’s Turning of the Sun that was accomplished by a very original set up. What I did to his original was stretch the fairly percussive track into something more ambient and rearrange the resulting lines before and after applying Melodyne’s adaptive Just Intonation. The result is quite different from the original and has become this consonant / dissonant tug of war ambient drone-ish piece.

James’ description of his original is as follows: “Contact mic into a little battery amp set to feedback level and turntable set in motion. There’s also some sounds of me moving around in a chair.” The rig is pictured below.

Capturing Paul (Acousmatic in Adaptive Just Intonation via Melodyne)

capturing_paul2 Spectrum analysis

Capturing Paul
What I did was modified Paul Mimlitsch’s prepared guitar track posted to Sound-In. In detail I deleted the highest and lowest notes, and retuned to 22 edo. Then I tuned it to 12 equal whole tone, and then to adaptive just intonation. I normalized the perceived tempo and then quantized the notes to triplet 16th and eight notes. Then I “pulled” the notes to be about 300% longer than originally. Lastly I used the Melodyne spectrum manipulation to kill all harmonics greater than #8. That made the sound a lot purer and a bit like brass in the final result.

Artist’s description:
I’m working on a new album that I’m pretty sure will be all ambient-ish – well my take on ambient.

I’m releasing this here as a preview.
