Loquebantur variis linguis in Adaptive JI normal and half speed

Wednesday, January 11th, 2017

The video is best viewed full screen. The half-speed version starts after a “note for nothing” to capture the reverb tail and a few seconds. The passing tones are very evident and dissonant in the half speed version. Loquebantur_variis_linguis PDF

turning of the sun inside out (Melodyne recomposition / acousmatic)

turning of the sun inside out is a recomposition of James Bailey’s Turning of the Sun that was accomplished by a very original set up. What I did to his original was stretch the fairly percussive track into something more ambient and rearrange the resulting lines before and after applying Melodyne’s adaptive Just Intonation. The result is quite different from the original and has become this consonant / dissonant tug of war ambient drone-ish piece.

James’ description of his original is as follows: “Contact mic into a little battery amp set to feedback level and turntable set in motion. There’s also some sounds of me moving around in a chair.” The rig is pictured below.

Capturing Paul (Acousmatic in Adaptive Just Intonation via Melodyne)

Capturing Paul
What I did was modified Paul Mimlitsch’s prepared guitar track posted to Sound-In. In detail I deleted the highest and lowest notes, and retuned to 22 edo. Then I tuned it to 12 equal whole tone, and then to adaptive just intonation. I normalized the perceived tempo and then quantized the notes to triplet 16th and eight notes. Then I “pulled” the notes to be about 300% longer than originally. Lastly I used the Melodyne spectrum manipulation to kill all harmonics greater than #8. That made the sound a lot purer and a bit like brass in the final result.

Artist’s description:
I’m working on a new album that I’m pretty sure will be all ambient-ish – well my take on ambient.

I’m releasing this here as a preview.

407crop Note Melodyne manual calls adaptive JI “dynamic” JI – see entry down the page by clicking the photo I took.


A Clean Machine – classical guitar re-composed to adaptive Just Intonation with a few “interesting” surprises introduced by Melodyne’s programming.

September (JI Ambient)

september_christiane


September – a collaboration of Christiane Offenbar, Meolog, and myself. All of the audio is derived from Christiane’s singing of Meolog’s poem which is below. The processing created tracks that were based on harmonic series started on 27.5 cents, 41.25 cents, and parallel tracks in a fugue at the octave, minor 3rd, 4th, and 5th.

Bat Bomb – Harmonic Series

Friday, September 16th, 2016

carlsbad_aaf_fire_after_bat_bomb_accident

Bat Bomb is part of an ongoing series of experiments to try to learn how to make aeolian harp type sounds. In this case I used Uhe’s Brazille with a patch that manipulated the overtone by adjusting the modwheel. Using my Linnstrument in MPE mode I was able to independently adjust the overtone (13 in total per note) by moving my finger in the “Y” dimension (which was routed to the modwheel channel control) and the root note from Carlos “Super JI” tuning by selecting the pad I played. The original patch had a lot of high end to it and are some time listening to it I decided to turn the filters down to try to get closer to a sine wave. Then I experimented with tempo. I find the 60 BPM version the most interesting at the time I am writing this post though there are some interesting peculiarities of each version. And, no, I don’t feel that came close to the aeolian harp, yet I think the experiment has its merit in learning sound design technique and audio result. Of course YMMV. I present the audio in the order I find most interesting. And yes, the bat bomb was real – click the photo to read about it as you listen.

Here is the audio spectrum analysis of the 60 BPM version. Click to enlarge.

Now Yer Talkin (JI piano)

Tuesday, August 23rd, 2016

now_yer_talking The score is here.


Now Yer Talkin is a short piece for piano. The composition is through composed. The tuning was developed by Doug Blumeyer and he asked for piano piece. This composition uses the comma shifts in the tuning to a fair degree in the right hand part. The tuning is here as a scala file.

Here is a half-time version to bring out the harmonies a bit more.
