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.

Welcome Gaia (106 edo)

welcome_gaia_score “Score” of performance

Welcome Gaia is a Linnstrument performance in MPE mode using a Diva patch in 106 edo (equal division of the octave). Even with the Linnstrument and its 200 pads 106 notes per octave puts a strain on what midi can currently do. In this performance I use pitch bends to extend the pitch space and also to add expression.

The Diva patch settings look like this
