Sound

LilyPond can produce MIDI output. The performance lacks lots of interesting effects, such as swing, articulation, slurring, etc., but it is good enough for proof-hearing the music you have entered. 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 the volume vary linearly between their two extremities. The fractions be adjusted by overriding the absolute-volume-alist defined in scm/midi.scm.

For each type of musical instrument (that MIDI supports), a volume range can be defined. This gives you basic equalizer control, which can enhance the quality of the MIDI output remarkably. You can add instruments and ranges or change the default settings by overriding the instrument-equalizer-alist defined in scm/midi.scm.

Both loudness controls are combined to produce the final MIDI volume.
