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 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.
