Development Guidelines for Creation of Polyhony Using SP-MIDI

While Scalable Polyphony-MIDI (SP-MIDI) [38] is a full-featured standard for synthesizing music, using a few guidelines SP-MIDI [38, 39] can be optimized for wireless devices. These guidelines can be grouped as optimizing individual notes, and to minimize the overall size of a melody.
