jack_midi_clock - JACK MIDI Beat Clock Generator
jack_midi_clock [ OPTIONS ] [JACK-port]*
jack_midi_clock - JACK app to generate MCLK from JACK transport.
-b <bpm>, --bpm <bpm> default BPM (if jack timecode master in not available) -B, --force-bpm ignore jack timecode master -d <sec>, --resync-delay <sec> seconds between 'song-position' and 'continue' message -J, --jitter-level <percent> add artificial jitter to the signal 0..20% default: off (0) -P, --no-position do not send song-position (0xf2) messages -T, --no-transport do not send start/stop/continue messages -s, --strict-bpm interpret tempo strictly as beats per minute (default is quarter-notes per minute) -h, --help display this help and exit -V, --version print version information and exit jack_midi_clock sends MIDI beat clock message if jack-transport is rolling. it also sends start, continue and stop MIDI realtime messages whenever the transport changes state (unless -T option is used). In order for jack_midi_clock to send clock messages, a JACK timecode master must be present and provide the tempo map (bar, beat, tick). Alternatively the -b option can be used to set a default BPM value. If a value larger than zero is given, it will be used if no timecode master is present. Combined with the -B option it can used to override and ignore the JACK timecode master and only act on transport state alone. Either way, jack_midi_clock will never act as timecode master itself. Note that song-position information is only sent if a timecode master is present ad the -P option is not given. To allow external synths to accurately sync to song-position, there is a two second delay between the 'song-position changed' message (which is not a MIDI realtime message) and the 'continue transport' message. This delay can be configured with the -d option and is only relevant for if playback starts at a bar|beat|tick other than 1|1|0 in which case a 'start' message is sent immediately. jack_midi_clock runs until it receives a HUP or INT signal or jackd is terminated.
