This message only needs to be sent once if a jump to a different position in the song is needed. This message consists of 3 bytes a status byte (decimal 242, hex 0xF2), followed by two 7-bit data bytes (least significant byte first) forming a 14-bit value which specifies the number of "MIDI beats" (1 MIDI beat = a 16th note = 6 clock pulses) since the start of the song. SPP can be used in conjunction with the above realtime messages for complete sync.
MIDI also specifies a System Common message called Song Position Pointer (SPP). MIDI beat clock defines the following real-time messages: Location information can be specified using MIDI Song Position Pointer (SPP, see below), although many simple MIDI devices ignore this message. MIDI beat clock differs from MIDI timecode in that MIDI beat clock is tempo-dependent. Those pulses are used to maintain a synchronized tempo for synthesizers that have BPM-dependent voices and also for arpeggiator synchronization. Clock events are sent at a rate of 24 pulses per quarter note. MIDI beat clock, or simply MIDI clock, is a clock signal that is broadcast via MIDI to ensure that several MIDI-enabled devices such as a synthesizer or music sequencer stay in synchronization.
