NAME

midiplay — play MIDI and RMID files

SYNOPSIS

midiplay

[-d devno] [-f file] [-l] [-m] [-p pgm] [-q] [-t tempo] [-v] [-x] [file ...]

DESCRIPTION

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:

-d 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.

-f file

specifies the name of the sequencer device.

-l

list the possible devices without playing anything.

-m

show MIDI file meta events (copyright, lyrics, etc).

-p 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.

-q

specifies that the MIDI file should not be played, just parsed.

-t 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.

-v

be verbose. If the flag is repeated the verbosity increases.

-x

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.

ENVIRONMENT

MIDIUNIT

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

FILES

/dev/music

MIDI sequencer device

HISTORY

The midiplay command first appeared in NetBSD 1.4.

BUGS

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.
