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, 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 separated by a colon. The time signature is 4:4 by default.
