BitWiz Harmonic Series Code

Saturday, May 6th, 2017


BitWiz is a $0.99 app that lets you run single line C code music generation algorithms. I used it to perform this piece by selecting code in sequence and using the X-Y manipulation when it was a part of the code. This software from Kymatica is for the iPad. The analysis shows that at least the first section is clearly non-12 equal. I didn’t analyze the rest, however, it seems to me to be almost next to impossible for a single line of code to generate something as unnatural as 12 equal.

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.

Linnstrument Improvisation in 106 edo (video)

Monday, January 16th, 2017



(best viewed full screen, video is 1080p)

Linnstrument Improvisation in 106 edo (audio only) is a moderate length piece that explores the wonderful soundscape that 106 edo can create. In a previous post I received this comment on Reddit’s microtonal subreddit “I generally like the sound of Bohlen-Pierce. I’m interested in this piece but confused by your methodology.” So I thought I would write something about my improvisation method as the video compiles. Essentially my approach to improvisations is an aurally informed pattern recognition with development. If you watch the video closely you will see places where I run into a note combination I don’t like and back away from it somewhat quickly and in others where I find a fingering I like and replicate it in either hand or as “blocks” played off against each other. 106 notes per octave makes melodic development especially challenging though it is rich harmonically with many nuances and to my ears a way of letting you settle into a harmony that may at first sound strange but re-orientates your ears to hear it as pleasing or at least interesting. Certainly with 106 edo it is very hard to get caught up in 12 edo sounding cliches! So I hope that gives a little bit of an answer to the question I received on Reddit. video download

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.
