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. <div><b>Web Extra: </b> 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.</div> <div><a href="http://csdl.computer.org/comp/mags/mu/2006/extras/u1056x1.wav">D_Eflat.wav</a> is a semitone interval.</div> <div><a href="http://csdl.computer.org/comp/mags/mu/2006/extras/u1056x2.wav">D_EhalfFlat.wav</a> is 3/4 tone interval.</div> <div><a href="http://csdl.computer.org/comp/mags/mu/2006/extras/u1056x3.wav">D_E.wav</a> is a whole tone interval.</div> <div><a href="http://csdl.computer.org/comp/mags/mu/2006/extras/u1056x4.wav">Fourinone.wav</a> is a scale of quarter-tones from D to E dividing the whole tone into four intervals.</div> <p>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.</p> <p> <a href="http://csdl.computer.org/comp/mags/mu/2006/extras/u1056x5.wav">Oshakelnabiorig.wav</a> 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 <em>Huzam</em>. <div><a href="http://csdl.computer.org/comp/mags/mu/2006/extras/u1056x6.wav">Oshakelnabisemi.wav</a> 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.</div></p>
