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 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.


   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

          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

   -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.


   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


   /usr/share/alsa/alsa.conf default rawmidi definitions
   /etc/asound.conf system-wide rawmidi definitions
   ~/.asoundrc user specific rawmidi definitions
