NAME

       amidi - read from and write to ALSA RawMIDI ports

SYNOPSIS

       amidi [-p port] [-s file | -S data] [-r file] [-d] [-t seconds] [-a]

DESCRIPTION

       amidi  is  a  command-line  utility  which  allows  one  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 support Standard MIDI (.mid) files, but aplaymidi(1) and arecordmidi(1) do.

OPTIONS

       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.

       -h, --help
              Help: prints a list of options.

       -V, --version
              Prints the current version.

       -l, --list-devices
              Prints a list of all hardware MIDI ports.

       -L, --list-rawmidis
              Prints all RawMIDI definitions.  (used when debugging configuration files)

       -p, --port=name
              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).

       -s, --send=filename
              Sends the contents of the specified file to the MIDI port.  The file  must  contain
              raw  MIDI  commands  (e.g.  a  .syx  file);  for  Standard  MIDI  (.mid) files, use
              aplaymidi(1).

       -r, --receive=filename
              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.

       -S, --send-hex="..."
              Sends the bytes specified as hexadecimal numbers to the MIDI port.

       -d, --dump
              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.

       -t, --timeout=seconds
              Stops receiving data when no data has been received for  the  specified  amount  of
              time.

              If  this  option  has not been given, you must press Ctrl+C (or kill amidi) to stop
              receiving data.

       -a, --active-sensing
              Does not ignore Active Sensing bytes (FEh) when saving or  printing  received  MIDI
              commands.

EXAMPLES

       amidi -p hw:0 -s my_settings.syx
              will send the MIDI commands in my_settings.syx to port hw:0.

       amidi -S 'F0 43 10 4C 00 00 7E 00 F7'
              sends an XG Reset to the default port.

       amidi -p hw:1,2 -S F0411042110C000000000074F7 -r dump.syx -t 1
              sends  a “Parameter Dump Request” to a GS device, saves the received parameter data
              to the file dump.syx, and stops after the device has finished sending data (when no
              data has been received for one second).

       amidi -p virtual -d
              creates a virtual RawMIDI port and prints all data sent to this port.

FILES
