Midiplay requires a midi synth to produce sounds. We dropped support
for OPL2-style chips, as we've two softsynths in ports to render
midi. Both already handle .mid files, so midiplay is not very useful
anymore.
Objections to remove it?
OK?

-.Nd play MIDI files
-.Sh SYNOPSIS
-.Nm midiplay
-.Op Fl gmqvx
-.Op Fl f Ar device
-.Op Fl t Ar tempo
-.Op Ar
-.Sh DESCRIPTION
-The
-.Nm
-command plays MIDI files.
-If no file name is given it will play from standard input;
-otherwise it will play the named files.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl f Ar device
-Specifies the name of the
-.Xr sndio 7
-MIDI device.
-.It Fl g
-Send a
-.Dq General MIDI On
-system exclusive message to the device.
-.It Fl m
-Show MIDI file meta events (copyright, lyrics, etc.).
-.It Fl q
-Do not play the MIDI file, just parse it.
-.It Fl t Ar tempo
-Specifies the tempo.
-Default is 100.
-.It Fl v
-Be verbose.
-If the flag is repeated, the verbosity increases.
-.It Fl x
-Play a small sample sound.
-.El
-.Sh SEE ALSO
-.Xr aucat 1 ,
-.Xr midi 4 ,
-.Xr sndio 7
-.Sh HISTORY
-The
-.Nm
-command first appeared in
-.Nx 1.4 .
