The 19th Sky of Semaphore

Saturday, April 8th, 2017


The 19th Sky of Semaphore is a composition for an imaginary chamber ensemble of two semaphore 19 tuned pianos. Photo by Chris Vaisvil
For comparison I present the same piece in 19 edo. If you listen closely you can hear slight beating in the opening 5th of the piece in the 19 edo version but is not present in the sempahore19 version.

Kontakt Factory String Ensemble in 106 edo

Wednesday, March 29th, 2017

click to make larger

Its something I never tried – for some reason I just thought that the Kontakt note per octave would stop at 99 notes per octave and just never tried to push it much past 26 edo or so. But, when investigating things related to my Parva I just let the note per octave number go…. well into the 300’s with no sign of hitting a limit. Of course, with only 128 midi notes, 300 divisions of an octave in one instrument is not terribly useful, though 106 edo is something I’ve come to really enjoy and the Kontakt Factory String Ensemble in all of its glory accepts this tuning with grace and poise. No chipmunks or weridly mutilated samples here! So, for my enjoyment and I hope yours as well, I present this short 106 edo improvisation. Clicking into the note per octave number lets you type in your desired division directly.
