Sh DESCRIPTION
The
Nm
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.
Pp
RMID files are Standard MIDI Files embedded in a RIFF container and
can usually be found with the
Sq rmi
extension.
They contain some
additional information in other chunks which are not parsed by
Nm
yet.
Pp
The program accepts the following options:
Bl -tag -width Fl
It Fl d Ar devno
specifies the number of the MIDI device used for output (as listed
by the
Fl l
flag).
There is no way at present to have
Nm
map playback to more than one device.
The default is device is given by environment variable
Ev MIDIUNIT .
It Fl f Ar file
specifies the name of the sequencer device.
It Fl l
list the possible devices without playing anything.
It Fl m
show MIDI file meta events (copyright, lyrics, etc).
It Fl p Ar 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
Nm
selectively map channels or instruments.
It Fl q
specifies that the MIDI file should not be played, just parsed.
It Fl s
send an
Dq ALL SOUNDS OFF
MIDI event.
Useful if an interrupted MIDI file left notes playing.
It Fl t Ar 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.
It Fl v
be verbose.
If the flag is repeated the verbosity increases.
It Fl x
play a small sample sound instead of a file.
El
Pp
A file containing no tempo indication will be played as if it specified
150 beats per minute.
You have been warned.
Sh ENVIRONMENT

Sh HISTORY
The
Nm
command first appeared in
Nx 1.4 .
Sh BUGS
It may take a long while before playing stops when
Nm
is interrupted, as the data already buffered in the sequencer will contain
timing events.
Use
Nm
with the
Fl s
option to silence any sounds left after an interrupted call.
