jack-smf-player - Standard MIDI File player for JACK MIDI




jack-smf-player [ -a input port ] [ -d ] [ -n ] [ -q ] [ -s ] [ -t ] [ -V ] [ -r rate ] [ file name ]


-a input port
  Automatically connect to the named input port. Note that this may cause problems with LASH.
-d When throttling, drop messages instead of delaying them.
-n Don’t start JACK transport at startup.
-q Be quiet, don’t print messages about SMF metaevents etc.
-s By default, jack-smf-player creates one output port, "midi_out", through which MIDI messages from all tracks are sent with their original MIDI channel number unchanged, and then one port per track, through which only MIDI messages from that particular track are sent with their MIDI channel reset to 0. That may cause problems with large number of tracks, as the number of JACK ports is a limited resource. Passing the "-s" option causes jack-smf-player to not create per-channel output ports. This option does not change behaviour of the "midi_out" port.
-t Do not use JACK transport. That means that playback will not start when the transport starts, will not seek when transport is relocated etc. Also, this flag will make jack-smf-player exit after the end of the song.
-V Print version number to standard output and exit.
-r rate
  Set output rate limit to rate, in Kbaud. Limit defined by the MIDI specification is 31.25. By default this parameter is zero, that is, rate limiting is disabled.


jack-smf-player is a tool to play SMF (Standard MIDI Format) files through JACK MIDI. At startup, it will load file which name is passed as a parameter, and, unless the "-n" option is given, rewind JACK transport to position zero and start playing. You can pause, play and seek using JACK transport, for example by using buttons under the display in qjackctl.
