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.
