midiplay — play MIDI and RMID files

midiplay [-lmqsvx] [-d devno] [-f file] [-p pgm] [-t tempo] [file ...]

The midiplay command plays MIDI and RMID files using the sequencer device. If no file name is given it will play from standard input, otherwise it will play the named files.

RMID files are Standard MIDI Files embedded in a RIFF container and can usually be found with the ‘rmi’ extension. They contain some additional information in other chunks which are not parsed by midiplay yet.

The program accepts the following options:

devno
specifies the number of the MIDI device used for output (as listed by the -l flag). There is no way at present to have midiplay map playback to more than one device. The default is device is given by environment variable MIDIUNIT.
file
specifies the name of the sequencer device.
list the possible devices without playing anything.
show MIDI file meta events (copyright, lyrics, etc).
pgm
force all channels to play with the single specified program (or instrument patch, range 1-128). Program change events in the file will be suppressed. There is no way at present to have midiplay selectively map channels or instruments.
specifies that the MIDI file should not be played, just parsed.
send an “ALL SOUNDS OFF” MIDI event. Useful if an interrupted MIDI file left notes playing.
tempo-adjust
specifies an adjustment (in percent) to the tempi recorded in the file. The default of 100 plays as specified in the file, 50 halves every tempo, and so on.
be verbose. If the flag is repeated the verbosity increases.
play a small sample sound instead of a file.

A file containing no tempo indication will be played as if it specified 150 beats per minute. You have been warned.

the default number of the MIDI device used for output. The default is 0.

midi(4)

The midiplay command first appeared in NetBSD 1.4.

It may take a long while before playing stops when midiplay is interrupted, as the data already buffered in the sequencer will contain timing events. Use midiplay with the -s option to silence any sounds left after an interrupted call.
