The Jacob Method refers to a method of playing the Linnstrument with Pianoteq that Jacob Barton discovered when we were together in Winston-Salem NC for the microfest. Essentially the method uses an extreme arpeggio setting on the Linnstrument with its pressure sensitive pads to create a piano voice that can swell. Take a listen…. 360 BPM 32nd note triplets.

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.
Distorted harmony in C major (intended to be 12 edo harmony which gets “bent”)
fanfare for a helium shrouded exoplanet (unconstrained pitch and percussion) for two ebows and two spring reverb units. Reverb unit MOD P-RMOD-8AB2A1B ($26 – 3 short springs) and Gibbs Manufacturing and Research unit salvaged from a Sears silver tone organ ($0 – 4 spring joined to make 2 long springs) – two tracks with each spring reverberation unit played by two ebows. In the midst of all of the noise incredible resonances with and without beating occur.
Cameron Bobro did something I thought impossible – used this piece as a ground to improvise clarinet over!
These are demonstration pieces of a technique
– not intentional pieces of music…
The title should really be SIGNAL looped analog synthesizer.
The basic idea is to use the Korg mini MS-20 as a sound source and use a delay in the signal path to return the delayed signal to the Korg’s frequency to control voltage converter. This is then sent to another delay / reverb to attempt to smooth some of the sharp changes. Invention 2 is the more musical of the two inventions and relies on sound on sound to fill out the signal. Invention 1 is using a long delay time. The graphic, crude as it is, contains the actual signal path. The motive is to find some other way than a sequencer or LFO to generate a self-performing analog system.
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.
