Kontakt Factory String Ensemble in 106 edo

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.

Parva Keyboard Slope Tuning with Melodyne Analysis

March 28th, 2017

Click on picture to enlarge and see the Melodyne analysis of the unknown tuning.

By using stacked keyboard note to frequency settings in the Parva modulation matrix I happened on this tuning that has a very nice sounding 318 cent near just minor third and a 1470 cent “9th” interval. This -almost- closes at the octave + tritone – which is close enough that Melodydne doesn’t show the octave with the default settings thinking it is an overtone.


This re-tuning technique relies on changing the midi note to pitch relationship called in some circles the “slope” of the keyboard.

Re-composition in 26 edo of Debussy’s String Quartet, Movement 1

March 13th, 2017

Picture by Chris Vaisvil

Using the first movement of Debussy’s string quartet I trans-tuned from 12 to 26 notes per octave and further developed the derivative by transposition and tempo adjustment. The result, to my ears, is much more early 21th century than late 19th century string quartet.
