.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 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
|
|
.Bl -tag -width MIDIUNIT
|
|
.It Ev MIDIUNIT
|
|

|
|
The default is 0.

.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.
