NAME
     arecordmidi - record Standard MIDI Files

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

DESCRIPTION
     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.

OPTIONS
     -h,--help
	    Prints a list of options.

     -V,--version
	    Prints the current version.

     -l,--list
	    Prints a list of possible input ports.

     -p,--port=client:port,...
	    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.

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

     -f,--fps=frames
	    Sets the SMPTE resolution, in frames per  second.	Possible  values
	    are 24, 25, 29.97 (for 30 drop-frame), and 30.

     -t,--ticks=ticks
	    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.

     -s,--split-channels
	    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.

     -m,--metronome=client:port
	    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 duration
	    1.

     -i,--timesig=numerator:denominator
	    Sets the time signature for the MIDI file and metronome.

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