LilyPond output file ending in .ly.
key signature, defaults to "c".
logical, print absolute pitches (unavailable in current package version).
integer, duration, quantize notes on duration.
logical, print explicit durations.
integer, duration, quantize note starts on the duration.
character vector, allow tuplet durations. See details.
logical, print additional information to console.
logical, treat all text as lyrics.
nothing returned; a file is written.
Under development/testing. See warning and details below.
This function is a wrapper around the midi2ly() command line utility
provided by LilyPond. It inherits all the limitations thereof.
LilyPond is not intended to be used to produce meaningful sheet music from
arbitrary MIDI files.
While lilypond() converts R code score() objects to LilyPond markup
directly, MIDI conversion to LilyPond markup by midily() requires LilyPond.
WARNING: Even though the purpose of the command line utility is to convert
an existing MIDI file to a LilyPond file, it nevertheless generates a
LilyPond file that specifies inclusion of MIDI output.
This means when you subsequently process the LilyPond file with LilyPond or
if you use miditab() to go straight from your MIDI file to pdf output,
the command line tool will also produce a MIDI file output. It will
overwrite your original MIDI file if it has the same file name and location!
allow_tuplets = NULL to disallow all tuplets. Fourth, eighth and sixteenth
note triplets are allowed. The format is a character vector where each
element is duration*numerator/denominator, no spaces. See default argument.
On Windows systems, it may be necessary to specify a path in tabr_options()
to both midi2ly and python if they are not already added to the system
PATH variable.
if (FALSE) { # \dontrun{
if(tabr_options()$midi2ly != ""){
midi <- system.file("example.mid", package = "tabr")
outfile <- file.path(tempdir(), "out.ly")
midily(midi, outfile) # requires LilyPond installation
}
} # }
