       arecordmidi - record Standard MIDI Files

       arecordmidi -p client:port[,...]	[options] midifile

       arecordmidi is a	command-line utility that records a Standard MIDI File
       from one	or more	ALSA sequencer ports.

       To stop recording, press	Ctrl+C.

	      Prints a list of options.

	      Prints the current version.

	      Prints a list of possible	input ports.

	      Sets the sequencer port(s) from which events are recorded.

	      A	client can be specified	by its number, its name, or  a	prefix
	      of  its name. A port is specified	by its number; for port	0 of a
	      client, the ":0" part of the port	specification can be omitted.

	      Sets the musical tempo of	the MIDI file, in  beats  per  minute.
	      The default value	is 120 BPM.

	      Sets  the	SMPTE resolution, in frames per	second.	 Possible val-
	      ues are 24, 25, 29.97 (for 30 drop-frame), and 30.

	      Sets the resolution of timestamps	(ticks)	in the MIDI  file,  in
	      ticks  per  beat	(when  using musical tempo) or ticks per frame
	      (when using SMPTE	timing).  The default value is 384  ticks/beat
	      or 40 ticks/frame, respectively.

	      Specifies	 that the data for each	MIDI channel should be written
	      to a separate track in the MIDI file.  This  will	 result	 in  a
	      "format  1"  file.   Otherwise,  when  there  is only one	track,
	      arecordmidi will generate	a "format 0" file.

	      Plays a metronome	signal on the specified	sequencer port.

	      Metronome	sounds are played on channel 10, MIDI notes  33	 &  34
	      (GM2/GS/XG  metronome standard notes), with velocity 100 and du-
	      ration 1.

	      Sets the time signature for the MIDI file	and metronome.

	      The time signature is specified as usual with two	numbers,  rep-
	      resenting	the numerator and denominator of the time signature as
	      it would be notated. The denominator must	be  a  power  of  two.
	      Both  numbers should be separated	by a colon. The	time signature
	      is 4:4 by	default.
