Perception-Based Microtuning over MIDI Networks
January-March 2006 (vol. 13 no. 1)
pp. 56-64
Ahmed Shawky Moussa, Cairo University, Egypt
MIDI has intrinsic limitations that have held back the development of flexible microtunable systems. I evaluate previous solutions and address the problem of pervasive microtuning in MIDI networks within the context of the general weaknesses and underusage of MIDI technology. I then describe my prototyped and patent-pending solution called U-Tune, which involves implementing pervasive microtuning over a MIDI network.
Web Extra: The following audio files are recording from a synthesizer using U-Tune for real-time microtuning. All the files are recorded from a synthesizer using U-Tune for realtime microtuning.
D_Eflat.wav is a semitone interval.
D_EhalfFlat.wav is 3/4 tone interval.
D_E.wav is a whole tone interval.
Fourinone.wav is a scale of quarter-tones from D to E dividing the whole tone into four intervals.

Here are two more files of the beginning of a popular theme used in Egyptian wedding parties, but this one is used as a wedding song.

Oshakelnabiorig.wav is the melody as it should sound with 3/4 tone intervals. The scale used in this song is a classic Arabic music scale, called Huzam.

Oshakelnabisemi.wav is the same melody when 3/4 tone intervals are unavailable. The resulting scale is a very different one. Although the melody wouldn't sound as harsh and bad as the previsous example when played in a different scale, still, if you're a paid musician you're guaranteed to have eggs and tomatoes thrown on you if you play it this way.
