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, respec‐
	      tively.

       -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 "for‐
	      mat 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	 ve‐
	      locity 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, representing 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  sepa‐
	      rated by a colon. The time signature is 4:4 by default.
