Mississinewa Lake (17 edo)

Sunday, April 16th, 2017


Mississinewa Lake (17 edo) was created by sampling my electric aeolian harp and using Kontakt to play the sample using the built in note per octave function on my DIY 17 note per octave midi controller. Effects were added in Kontakt and Sonar.

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].

Recomposition Using Celemony’s Melodyne Editor

Sunday, January 15th, 2017


Best viewed at the highest resolution available. The native video is in 1080p

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.

Demo of Shoom, a Microtonal iPad App

Thursday, December 29th, 2016

I take trip through Shoom after Keenan Lawler mentioned it, and I found I actually had it installed. It is a superb microtonal aware synthesizer that is also a controller. My tour is a bit leisurely and only goes into a bit of what this program can do. It is highly recommended. It was $5.99 when it was first released, currently I believe the app store price is $9.99 – still quite affordable. The noise you hear in places are the actual (and unusual) preset settings of the app.
