A growing collection of microtonal works performed with the Lumatone isomorphic keyboard.

EDO stands for “equal division of the octave”, a tuning system that divides the octave into a whole number of steps. The tuning system most commonly used in Western music is 12-tone equal temperament (12-TET), sometimes referred to as 12-EDO. A tuning like 19-EDO splits the octave into 19 equal steps, adding 7 new notes: sharps and flats become distinct notes (D# no longer equals Eb), along with adding B# and E#. An octave can be split into any number of equal divisions, and EDO tunings are some of the more accessible microtonal tunings. There’s an endless world of theory (with lots of ratios) when it comes to microtonality that could take more than a lifetime to study; I’m certainly no expert, but I do love composing in tunings beyond 12-TET. My current favorites: 7-EDO, 19-EDO, 22-EDO.

The Lumatone is a powerful MIDI controller that allows for microtonal tunings to be easily visualized and performed compared to a traditional keyboard. I use it in much of my work, including controlling modular synthesizers, LED lights over DMX, and for microtonal compositions.
