midi_play: Play or convert a midi file

Description

Play a midi file to your audio device, render it to a file, or parse the raw data. Additional settings can be specified, see fluidsynth_setting_list for available options.

Usage

midi_play(
  midi = demo_midi(),
  soundfont = soundfont_path(),
  audio.driver = NULL,
  settings = list(),
  verbose = interactive()
)
midi_convert(
  midi = demo_midi(),
  soundfont = soundfont_path(),
  output = "output.mp3",
  settings = list(),
  verbose = interactive()
)
midi_read(midi = demo_midi(), verbose = FALSE)
demo_midi()

Value

midi_read returns data frame with midi events.

Arguments

midi: path to the midi file
soundfont: path to the soundfont
audio.driver: which audio driver to use, see fluidsynth docs
settings: a named vector with additional settings from fluidsynth_setting_list()
verbose: print some progress status to the terminal
output: filename of the output. The out

Details

The midi_convert function internally uses fluidsynth to generate a raw wav file, and then av::av_audio_convert() to convert into the requested about format. See av::av_muxers() for supported output formats and their corresponding file extension.

You need a soundfont to synthesize midi, see the soundfonts page. On Linux you may also need to specify an audio.driver that works for your hardware, although on recent distributions the defaults generally work.

Examples

Run this code

df <- midi_read(demo_midi())
