The video is of the base 22″ Wuhan gong hit after 35x Paulstretch with the noise reduction on. What remains are the isolated gong tones buried in the crash and the drawn out “hum” tones. Caution – there are some very loud, high pitches. Best viewed at the highest resolution you can manage.
With the gong tones in Melodyne I was able to retune them to 22 edo porcupine with magic 7th variant (below) – for my taste I used Melodyne to remove the highest “hum” note which I disliked. Retuned gong download
I put a GK-3 hex pick up on my 19 edo guitar – what follows are three demonstration pieces that rely on the pitch interpretation of the GP-10 processor. My overall impression that this was successfully accomplished as you can clear hear places where I pushed a decidedly non-12 equal note(s) through the system.
For Chamber Ensemble, Grain Silo, and Wrecking Ball in 1/4 comma meantone is a semi-aleatoric recomposition of midi extracted from a multitrack analog synthesizer piece called “Iron Harvest“.
Using Melodyne Single Track I extracted the midi from each analog synthesizer track. This was rather interesting in itself since non-traditional pitched elements of that performance were interpreted as pitched material. So, for example, a change in filter resonance created an additional pitch. This rich input material was then edited and used as a score for the the ensemble.
The ensemble consists of solo strings (violin, viola, cello, and double bass), solo alto flute, bass trombone, contra-bassoon, bass clarinet and harp (with arpeggio applied) from the Garritan Personal Orchestra sound set with the included 1/4 meantone tuning (below). The video was shot with a Fujifilm exr F660 while on a trip to a different destination, in other words, “a happy accident”.
The sound of the wrecking ball and the collapsing grain silo are used as found sound percussive elements in this piece. The video sound track was cleaned by noise reduction and application of a noise gate to keep most of the sound of the strikes and falls minus the background traffic noise.
