17 edo guitar in “a minor” with “C harmony”

Saturday, July 22nd, 2017


I improvised with my 17 edo guitar through a GT-10 using its C harmony patch – the resulting tuning is above. I think it sounds interesting at times.
Here is the adjusted (nomalized to 0 cent tonic) probabilistic applied tuning.

The Abyssal Plains

Sunday, June 25th, 2017

The Abyssal Plains is a piece performed on an Alesis Q88 using Scala to on-the-fly retune a Parva 8 voice synthesizer with added Native Instruments Guitar Rig 5 effects recorded and mastered in Sonar Platinum. The tuning has a degree of uncertainty due to pitch bend shifts around a target of 16 edo.

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.
