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

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.

Microtonal Gestrument Demo Video

Tuesday, December 27th, 2016

A video demo of the Gestrument, an algorithmic music composition iPad program that supports alternate tunings. It works hand in hand with ScaleGen (not shown here) for $13.99 bought as a bundle. Its a great value and has a long list of features such as morphing of tunings, recording, a nice selection of voices and output of midi.

LinnStrument as a Microtonal Controller – Split Mode

Wednesday, December 7th, 2016

Click to enlarge, right-click to download

Here is a short demonstration video of the split mode as implemented in the original Linnstrument. By using the split mode one can access all 200 pads. With a judicious selection of synthesizer and range one can extend a tuning well beyond the current midi standard of 128 notes. The short demonstration piece uses two non-octave tunings => 5/4 divided into 4 and 5/4 divided into 8 notes respectively.

The Temple of Clouds is a combination of processed electric 17 edo guitar and timelapse video – at about 5 through 6 minutes you can see a thunderstorm come through. The video was recorded with a Brinno TLC200 time lapse camera.The tuning is unknown though a 17 edo guitar was used to generate the starting point.

Animated Score Rite of Spring Fragment D in Adaptive JI for Brass Ensemble

Wednesday, July 20th, 2016


I have been archiving past projects and I ran across this fragment of The Rite of Spring (French: Le Sacre du printemps; Russian: «Весна священная», Vesna svyashchennaya, ‘sacred spring’) and decided it would be interesting to render it in adaptive just intonation since that has been a recent topic of interest on the Facebook group Xenharmonic Alliance II. The video is an overlay of the score and the real time adjustments made by the Kontakt included factory script. I selected the factory brass ensemble which in my opinion rendered a nice version of one of my favorite passages of the piece. YMMV of course. You can find the video here for download.

NOTE: Sonar has a a very odd sense of accidentals if you do not explicitly apply a key.
