+.Sh NAME
+.Nm mididump
+.Nd dump MIDI events
+.Sh SYNOPSIS
+.Nm
+.Op Fl t
+.Ar device
+.Sh DESCRIPTION
+The
+.Nm
+utility is used to dump MIDI 1.0 events in real-time.
+.Pp
+The options are as follows:
+.Bl -tag -width "-t"
+.It Fl t
+Print "Timing Clock" events.
+These events are not printed by default, as they tend to clutter output.
+.El
+.Pp
+The
+.Ar device
+argument corresponds to the MIDI device (e.g.
+.Pa /dev/umidi0.0 ) .
