# Send an individual MIDI clock tick

``

    midi_clock_tick   ()

Sends a MIDI clock tick message to all connected devices on all channels. Use the `port:` and `channel:` opts to restrict which MIDI ports and channels are used.

Typical MIDI devices expect the clock to send 24 ticks per quarter note (typically a beat). See `midi_clock_beat` for a simple way of sending all the ticks for a given beat.
