Using the first movement of Debussy’s string quartet I trans-tuned from 12 to 26 notes per octave and further developed the derivative by transposition and tempo adjustment. The result, to my ears, is much more early 21th century than late 19th century string quartet.
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].

By using Celemony’s Melodyne Editor I rearrange the notes within a droning sample from my DIY electric aeolian harp. The tuning is nominally Bohlen-Pierce (stock with Melodyne) but the nature of the aeolian harp means additional pitches are present.

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.
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.

off tracks age is an aeolian harp sample that was recomposed by using Melodyne 4’s adaptive Just Intonation and rhythm normalization functions and then the exported result was modified using Native Instrument’s Guitar Rig 5 and Cakewalk Sonar’s Breverb.
A Clean Machine – classical guitar re-composed to adaptive Just Intonation with a few “interesting” surprises introduced by Melodyne’s programming.
September – a collaboration of Christiane Offenbar, Meolog, and myself. All of the audio is derived from Christiane’s singing of Meolog’s poem which is below. The processing created tracks that were based on harmonic series started on 27.5 cents, 41.25 cents, and parallel tracks in a fugue at the octave, minor 3rd, 4th, and 5th.
noch einmal auf
und lichtet sich
mit den bäumen
mit dem wind
standing in the cornfield you watch the corn grow and
the searing hot days pass on to night to day to night to day,
taller and taller, until you are one with all there is…
for you are one of them…
your roots dig soil,
your stalk stretches greedily for every ray of the murdering sun
in the anguish of a midsummer’s thirst…
