Parva Keyboard Slope Tuning with Melodyne Analysis

Tuesday, March 28th, 2017

Click on picture to enlarge and see the Melodyne analysis of the unknown tuning.

By using stacked keyboard note to frequency settings in the Parva modulation matrix I happened on this tuning that has a very nice sounding 318 cent near just minor third and a 1470 cent “9th” interval. This -almost- closes at the octave + tritone – which is close enough that Melodydne doesn’t show the octave with the default settings thinking it is an overtone.


This re-tuning technique relies on changing the midi note to pitch relationship called in some circles the “slope” of the keyboard.

TraderJoe’s Cantus Firmus in 22 edo SuperPyth

Saturday, February 25th, 2017

click on picture for score
The Trader Joe’s Cantus Firmus as a non-strict fugue – in double time as written for woodwinds, flue, alto flue, clarinet, contrabasoon in SuperPyth mode 1
and in half time for those who like the harmonies to linger a bit more.

I’m not sure, after spending have a day sorting this out more or less to my… level of being able to kick it out the door, that while cool because of its source from food packaging with ancient music as its box, that this is a good exercise. Its big, the melody itself is not (to me) very appealing. See what you think.

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.

Being Califlower (12 equal – ImprovFriday mash)

Sunday, February 7th, 2016


Being Cauliflower (feat. Shane Cadman, Chris Vaisvil, Jude Cowan and mashed by Steve Layton) – Nearly every musician has had the experience where they join in a free-form unplanned improvisation and magic happens in the room as everyone seem to pull their parts from the air and make a cohesive whole. As one who has experienced that I have to say it is an awesome feeling of being “plugged in”. What is even more incredible is when this happens when the respective musicians can’t hear each other and separated by hundreds or thousands of miles across the internet. Steve Layton in 2012 took a number of separately recorded tracks for the then ImprovFriday (now and put them together with little editing and the result is one of my favorite collaborative tracks “Being Califlower”. I hope you enjoy it as well.

even the best of intentions (experimental)

This is not nice melodic music
– it is a harsh exploration of a technique!

even the best of intentions is an exercise in transforming audio. I used a sound effects CD ripped to my iPod as the source for the Korg MS-20 mini’s signal in. While it played I manipulated the settings on the synthesizer. If you listen closely you can at times hear a bit of the original signal leaking into the output. Except for editing out silence I applied no effects or other manipulation of the output.

A Trip to the MSI in JI (video)

A montage created from a trip to the Museum of Science and Industry in Chicago. All of the audio in this video comes from the visit processed to some degree. The “music” is tuned to Just Intonation by Melodyne. This wide-screen video is best enjoyed full screen since there is significant detail.Untitled

22″ Wind Gong Audio Spectrum Manipulation With Animated Visualization

Sunday, July 5th, 2015

The video is of the base 22″ Wuhan gong hit after 35x Paulstretch with the noise reduction on. What remains are the isolated gong tones buried in the crash and the drawn out “hum” tones. Caution – there are some very loud, high pitches. Best viewed at the highest resolution you can manage.

The above is the audio spectrum of the noised reduced and 35x stretched track using a FFT transform. Click the picture to enlarge it.

With the gong tones in Melodyne I was able to retune them to 22 edo porcupine with magic 7th variant (below) – for my taste I used Melodyne to remove the highest “hum” note which I disliked.

For Chamber Ensemble, Grain Silo, and Wrecking Ball in 1/4 comma meantone with Video

Sunday, June 28th, 2015

For Chamber Ensemble, Grain Silo, and Wrecking Ball in 1/4 comma meantone is a semi-aleatoric recomposition of midi extracted from a multitrack analog synthesizer piece called “Iron Harvest“.

Using Melodyne Single Track I extracted the midi from each analog synthesizer track. This was rather interesting in itself since non-traditional pitched elements of that performance were interpreted as pitched material. So, for example, a change in filter resonance created an additional pitch. This rich input material was then edited and used as a score for the the ensemble.

The ensemble consists of solo strings (violin, viola, cello, and double bass), solo alto flute, bass trombone, contra-bassoon, bass clarinet and harp (with arpeggio applied) from the Garritan Personal Orchestra sound set with the included 1/4 meantone tuning (below). The video was shot with a Fujifilm exr F660 while on a trip to a different destination, in other words, “a happy accident”.

The sound of the wrecking ball and the collapsing grain silo are used as found sound percussive elements in this piece. The video sound track was cleaned by noise reduction and application of a noise gate to keep most of the sound of the strikes and falls minus the background traffic noise.

Entropic Sculpture

Thursday, April 2nd, 2015


Entropic Sculpture is an accidental interpenetration of a post-modern sculptural art genre created from analog synthesizer settings my son left for me and then I used and eventually mutated. I ran this mix out of Sonar pretty hot and generated some distortion. Honestly I liked the effect and therefore left it as it was. The tuning is technically 12 but has more shades than plain ole piano music.
