In this presentation I use Jam Origin’s MIDI Guitar to send a microtonally retuned MIDI stream to Kontakt 5’s string ensemble. The guitar was run through the cakewalk amp sim. In the top graphic I show where the microtonal midi machine is loaded (lower right) and in the next graphic I show the interface of the microtonal machine. A key is to enable the same amount of pitch bend in MIDI guitar as well as the VSTi you are using. In this case it was the standard 2 whole tones. In the sound demo you can hear the 12 equal guitar playing single notes to full chords in 12 equal and at the same time the Kontakt strings in 125 cents per step tuning driven by the Jam Origin included audio VSTi. In sonar be sure to enable MIDI guitar’s midi out in order to put it into the list of your VSTi.

The midi file that I found is of medium quality and this is decidedly a demonstration piece – this tune was chosen because it is a favorite of Gene’s. To get around having to transpose each note individually or as a pitchclass I use the method of picking 12 notes out of the 27 note set and used that to retuned Garritan Concert and Marching Band samples. The actual tuning is listed below. I think it notable that the rather large deviations from 12 equal, where each step is exactly 100 cents, is not very evident if at all.

The Coming Storm is a 25 minute recording of a thunderstorm that approaches and then releases a deluge of rain. The sounds are a combination of wind blown harmonics, the clicks of lightning, and then play of the strings of the harp by the rain as well as wind. There is some residual background noise that I can’t remove without removing the lightning strikes so it was left in. A surprising (to me) variety of sounds result from this onslaught of nature. Metallic clinks, almost light saber-esque stabs, and the sound of huge things being dragged violently across the harp. Starts out quiet and gets pretty loud.
This is a 24 minute long piece, it will take a while to load and play.
What Have I Done is an ambient setting of a poem I wrote which was recited by Bethan Mathis. We are slowly working on an album together. The music are selected recordings of my Electric Aeolian Harp. Additionally there are field recordings that I made and from Freesound.org field recordings by martian, digifishmusic and looijenga.
My friend Phil loaned a “squirrel cage” furnace blower with a 6 amp motor to help me explore my DIY Electric Aeolian Harp. I’m doing these experiments to help with the design of an eventual hard wood, moisture harden version with gear tuners, or possibly an open cage omnidirectional version (or heck, why not both??). I’m also keen on seeing what I can do to change the harmonic series response interactively with the environment. Having a such a powerful fan imitates a strong gale (I felt a definite chill, my eyes teared, and my nose ran using this fan!). This is a long video and certainly not an exciting film but perhaps of interest of those who are making their own version of an aeolian harp. During the film I mute and pluck stings, try some tuning variation and use the zither pin key as a slide.

The Collected Speeches of Joseph Stalin is a piano improvisation in 19 equal. It features the logidy UMI3 pedal which gives me access to the 3 other piano pedals besides sustain that pianoteq supports; Una Corda, Sostenuto, and used here at ~5 minutes the Harmonic pedal which doesn’t exist in a real piano. The logidy pedal is the most cost effective solution to accessing these other pedals ($80 Amazon) and is fully programmable and even supports attaching an expression pedal. Obviously this is also a great solution for owners of an AXiS 49 which for some inexplicable reason doesn’t have sustain pedal capability.
Here is a comparison of La messa de Nostre Dame Sanctus in different tunings as rendered via Kontakt’s choir sample set. The midi file I used is here. (S.Takahata transcribed the piece to midi) The score with Sonar’s brain-dead accidentals is here.
First version uses Kontakt’s built in adaptive JI (adaptive JI = dynamic pure tuning like this live example video that shows the changes in intonation in real time https://www.youtube.com/watch?v=WB6I6EWWdr4 )

On Avocado Trees is an ambient piece created from manipulating steel string acoustic guitar through several effects.
