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 configura- tion 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 configura- tion 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 arecord- midi(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 print- ing 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 -SF0 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.
