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 result 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.
