LinnStrument as a Microtonal Controller – Split Mode

Wednesday, December 7th, 2016

Click to enlarge, right-click to download

Here is a short demonstration video of the split mode as implemented in the original Linnstrument. By using the split mode one can access all 200 pads. With a judicious selection of synthesizer and range one can extend a tuning well beyond the current midi standard of 128 notes. The short demonstration piece uses two non-octave tunings => 5/4 divided into 4 and 5/4 divided into 8 notes respectively.

off tracks age is an aeolian harp sample that was recomposed by using Melodyne 4’s adaptive Just Intonation and rhythm normalization functions and then the exported result was modified using Native Instrument’s Guitar Rig 5 and Cakewalk Sonar’s Breverb.

Melodyne Deep Dive in an Aeolian Harp Sound Sample

Saturday, August 27th, 2016

The above aeolian harp sample (from 2014-11-07 21:12:51 pm) had an interesting sonority to my ears. I wanted to find out what the chord was so that I could reproduce it. So I put it into Melodyne to analyze the chord. As I listened to the file and looked at the display there seemed to be a bit of a disconnect. So I dissected the sample (Sections labeled A through H by ear – there are two disjunct groups) into individual files. Then I normalized them and ran them through Melodyne once more. The resulting sound files and analysis are below. You will notice that in some cases what was a single tone in the original now breaks into more than one note. In other cases more than one note is heard but Melodyne doesn’t show them as separate – I think in these cases the program analysis is tagging them as part of the harmonics which is shown below the main window of the program. Since an aeolian harp is a special case where the harmonics of this is a special case, interesting though it may be. Most of the dead air was removed from the A through H audio samples.

The labeled file below is in Hz. You can download the audio and graphics here as a zip file.

The Complex Plane (BP Guitar)

The Complex Plane is a two track Bohlen-Pierce guitar rehearsed (and therefore directed) improvisation with backing drums. Click on the graphic above to see the guitar and information on this tuning.

Red Sands Maunsell Forts

Redsandsforts

Red Sands Maunsell Forts is quasi-ambient piece constructed from loops taken from a 17 edo guitar improvisation and the subsequent loops processed and live sequenced using Sonar’s matrix view (the graphic below). While it doesn’t have the flexibility of Albelton Live, I find the the constructs to be interesting despite being laborious to set up.

The McMurdo Session – Xenharmonic Gang of Five

Saturday, July 30th, 2016

xenharmonic_gang_of_five Left to Right Andrew Heathwaite, Aaron Krister Johnson, Jacob Barton, Dan Stearns and myself

These recordings are totally unrehearsed improvisations that took place at my home. As a consequence there is wandering and going down paths that were discarded. I attempted to curate the best parts of an all day session. Much of the music wouldn’t make sense without enduring the development before something jelled. Two pieces of this session were previously released and are included here to complete the session. Instruments – voice, trombone, udderbot, clarinet, 15 edo, 17 edo, 19 edo, 20 edo, 22edo guitars and fretless banjo, guitar and bass, gongs, Tibetan singing bowls, DIY erhu, 31 edo bouzuki, various electronics and percussion. We freely mixed tunings and our compositional goal was to have a good time! We hope you enjoy these recordings.

Perseus Cluster (processed electric aeolian harp)

NASA-PerseusGalaxyCluster-ChandraXRayObservatory-20140624


Perseus Cluster (processed electric aeolian harp) is an ambient directed aleatoric piece – the wind played the aeolian harp after I tuned it. I recorded the result and then I processed the harp through a battery of effects to create an ambient piece that consists of a drone of processed harmonics.

37 edo Aeolian Harp Prelude

37 edo Aeolian Harp Prelude is a piece composed by modifying with Melodyne a electric aeolian harp drone chord played by the wind. The approximate original tuning was re-tuned to 37 edo from an imported a scala file I made and then the piece composed by adjusting the individual notes.
