aplaymidi - play Standard MIDI Files
aplaymidi -p client:port[,...] [-d delay] midifile ...
aplaymidi is a command-line utility that plays the specified MIDI file(s) to one or more ALSA sequencer ports.
Prints a list of options.
Prints the current version.
Prints a list of possible output ports.
Sets the sequencer port(s) to which the events in the MIDI file(s) are sent. A client can be specified by its number, its name, or a prefix of its name. A port is specified by its number; for port 0 of a client, the ":0" part of the port specification can be omitted. For compatibility with pmidi(1), the port specification is taken from the ALSA_OUTPUT_PORTS environment variable if none is given on the command line.
Specifies how long to wait after the end of each MIDI file, to allow the last notes to die away.
