10.2.1 Creating MIDI files

To create a MIDI from a music piece of music, add a \midi block to a score, for example,

\score {
  ...music...
  \midi { \tempo 4=72 }
}

The tempo is specified using the \tempo command. In this example the tempo of quarter notes is set to 72 beats per minute.

If there is a \midi command in a \score, only MIDI will be produced. When notation is needed too, a \layout block must be added

\score {
  ...music...
  \midi { \tempo 4=72 }
  \layout { }
}

Ties, dynamics, and tempo changes are interpreted. Dynamic marks, crescendi and decrescendi translate into MIDI volume levels. Dynamic marks translate to a fixed fraction of the available MIDI volume range, crescendi and decrescendi make the volume vary linearly between their two extremes. The fractions can be adjusted by dynamicAbsoluteVolumeFunction in Voice context. For each type of MIDI instrument, a volume range can be defined. This gives a basic equalizer control, which can enhance the quality of the MIDI output remarkably. The equalizer can be controlled by setting instrumentEqualizer.
