amidi − read from and write to ALSA RawMIDI ports
amidi [−p port] [−s file | −S data] [−r file] [−d] [−t seconds] [−a]
amidi is a command-line utility which allows to receive and send SysEx (system exclusive) data from/to
external MIDI devices. It can also send any other MIDI commands.
amidi handles only files containing raw MIDI commands, without timing information. amidi does not sup-
port Standard MIDI (.mid) files, but aplaymidi(1) and arecordmidi(1) do.
Use the −h, −V, −l, or −L options to display information; or use at least one of the −s, −r, −S, or −d options
to specify what data to send or receive.
Help: prints a list of options.
Prints the current version.
Prints a list of all hardware MIDI ports.
Prints all RawMIDI definitions. (used when debugging configuration files)
Sets the name of the ALSA RawMIDI port to use. If this is not specified, amidi uses the default
port defined in the configuration file (the default for this is port 0 on card 0, which may not exist).
Sends the contents of the specified file to the MIDI port. The file must contain raw MIDI com-
mands (e.g. a .syx file); for Standard MIDI (.mid) files, use aplaymidi(1).
Writes data received from the MIDI port into the specified file. The file will contain raw MIDI
commands (such as in a .syx file); to record a Standard MIDI (.mid) file, use arecordmidi(1).
amidi will filter out any Active Sensing bytes (FEh), unless the −a option has been given.
Sends the bytes specified as hexadecimal numbers to the MIDI port.
Prints data received from the MIDI port as hexadecimal bytes. Active Sensing bytes (FEh) will
not be shown, unless the −a option has been given.

This option is useful for debugging.
Stops receiving data when no data has been received for the specified amount of time.
