Micronation is an audio experiment where I took a ~30 seconds of aeolian harp captured during a high wind event and used Melodyne to determine each of four root notes by frequency. [The strings were tuned justly by ear but drift after several hours exposure to the elements outside, especially due to temperature changes] Then I used Paul’s Extreme Sound Stretch to isolation each vertical harmonic structure based upon the roots determined by Melodyne (10 harmonics high by 25 cents wide)and exporting the four files. Then I used Sonar to sequence the exported wav files and applied reverb, EQ, and tape simulation. The experimentally determined roots are 92 Hz, 118 Hz[59/46], 140 Hz[35/23], and 184 Hz [ 2/1 the octave of 92].

By using Celemony’s Melodyne Editor I rearrange the notes within a droning sample from my DIY electric aeolian harp. The tuning is nominally Bohlen-Pierce (stock with Melodyne) but the nature of the aeolian harp means additional pitches are present.

I take trip through Shoom after Keenan Lawler mentioned it, and I found I actually had it installed. It is a superb microtonal aware synthesizer that is also a controller. My tour is a bit leisurely and only goes into a bit of what this program can do. It is highly recommended. It was $5.99 when it was first released, currently I believe the app store price is $9.99 – still quite affordable. The noise you hear in places are the actual (and unusual) preset settings of the app.

nearly an eternity – processed electric aeolian harp
You can see the tuning in Melodyne
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.
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.
