Midi2ly translates a MIDI input file to a LilyPond source file.
MIDI (Music Instrument Digital Interface) is a standard for digital instruments: it specifies cabling, a serial protocol and a file format. The MIDI file format is a de facto standard format for exporting music from other programs, so this capability may come in useful when you want to import files from a program that has no converter for its native format.
Midi2ly will convert tracks into Staff and channels into Voice contexts. Relative mode is used for pitches, durations are only written when necessary.
It is possible to record a MIDI file using a digital keyboard, and
then convert it to .ly
. However, human players are not
rhythmically exact enough to make a MIDI to LY conversion trivial.
midi2ly tries to compensate for these timing errors, but is not very
good at this. It is therefore not recommended to use midi2ly for
human-generated midi files.
Hackers who know about signal processing are invited to write a more robust midi2ly. midi2ly is written in Python, using a module written in C to parse the MIDI files.
It is invoked as follows:
midi2ly [option]... midi-file
The following options are supported by midi2ly:
-a, --absolute-pitches
-d, --duration-quant=
DUR
-e, --explicit-durations
-h,--help
-k, --key=
acc[:
minor]
-o, --output=
file
-s, --start-quant=
DUR
-t, --allow-tuplet=
DUR*
NUM/
DEN
-V, --verbose
-v, --version
-w, --warranty
-x, --text-lyrics
