haircut (DIY electric cello conversion from bass)

Friday, November 17th, 2017

haircut” is mainly an experiment with “inserting” an external effect into my DAW (Sonar) on a pre-recorded track. So in this case I get to manipulate the effect real time.

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.

Parva Keyboard Slope Tuning with Melodyne Analysis

Tuesday, 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.

This is not art.

The Era of Fake News

Saturday, February 18th, 2017

The Era of Fake News was done by using a 70’s fuzz pedal with a cardioid mic to sample gongs, cymbals, singing bowls and chimes. These samples were then loaded into Sonar’s Matrix View and used to create a performance which was captured. Massive reverb was added.

The Era of Fake News Sanatized is the same track using Paul’s Extreme Stretch’s tonal only switch – no time stretching.

If you want to sample it – please give me a credit and link back.

Mt. Herschel is an practiced improvisation using pianoteq in 10 edo and my Korg MS2000 in a close to 10 edo tuning by using keyboard slope. Below is the Melodyne output of a short section of the tuning played “chromatically” with a softer timbre.

Capture Solving Thou words by meolog, sung by Christiane Offenbar, translated by Heinz Bohlen, composition Chris Vaisvil for synthesizers in 43 note overtone series, 11 limit 12 note tuning from Scala archive, 22 edo guitar, percussion and Christiane’s free a Capella singing.

even the best of intentions (experimental)

This is not nice melodic music
– it is a harsh exploration of a technique!

even the best of intentions is an exercise in transforming audio. I used a sound effects CD ripped to my iPod as the source for the Korg MS-20 mini’s signal in. While it played I manipulated the settings on the synthesizer. If you listen closely you can at times hear a bit of the original signal leaking into the output. Except for editing out silence I applied no effects or other manipulation of the output.
