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.
