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 and Clock bytes (FEh, F8h), unless the -a or  -c  options
              have 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 and Clock bytes
              (FEh, F8h) will not be shown, unless the -a or -c options have 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.

       -c, --clock
              Does not ignore Clock bytes (F8h) when saving or printing received MIDI commands.

       -i, --sysex-interval=mseconds
              Adds a delay in between each SysEx message sent to a device. It is useful  when  sending  firmware
              updates via SysEx messages to a remote device.

EXAMPLES

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

       amidi -p hw:1,0,0 -s firmware.syx -i 100
              will  send  the  MIDI  commands  in  firmware.syx  to port hw:1,0,0 with 100 milliseconds delay in
              between each SysEx message.

       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.
