APLAYMIDI(1)                General Commands Manual               APLAYMIDI(1)



NAME
       aplaymidi - play Standard MIDI Files


SYNOPSIS
       aplaymidi -p client:port[,...] [-d delay] midifile ...


DESCRIPTION
       aplaymidi  is  a  command-line  utility  that  plays the specified MIDI
       file(s) to one or more ALSA sequencer ports.


OPTIONS
       -h, --help
              Prints a list of options.


       -V, --version
              Prints the current version.


       -l, --list
              Prints a list of possible output ports.


       -p, --port=client:port,...
              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.

              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.


       -d, --delay=seconds
              Specifies  how  long to wait after the end of each MIDI file, to
              allow the last notes to die away.


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