APLAYMIDI(1) General Commands Manual APLAYMIDI(1)


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.

Changes the sequencer client to the given MIDI version and outputs via the UMP packets instead of legacy sequencer events. As of now, the only supported version is 1.

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.

Multiple ports can be specified to allow playback of MIDI file(s) that contain events for multiple devices (ports), as specified by "Port Number" meta events.

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.


aplaymidi handles "Port Number" meta events, but not "Port Name" meta events.
