       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 values 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 re‐
              sult 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 duration 1.

              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.
