Details

Under development/testing. See warning and details below.

Convert a MIDI file to a pdf or png music score using the LilyPond music engraving program. Output format is inferred from file extension. This function is a wrapper around midily(), the function that converts the MIDI file to a LilyPond (.ly) file using a LilyPond command line utility.

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!

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.

Examples

if (FALSE) { # \dontrun{
if(tabr_options()$midi2ly != ""){
  midi <- system.file("example.mid", package = "tabr")
  outfile <- file.path(tempdir(), "out.pdf")
  miditab(midi, outfile, details = FALSE) # requires LilyPond installation
}
} # }
