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. Clock events are sent at a rate of 24 pulses per quarter note .
These include a large, very granular tempo slider similar to the sliders found on a modern phonograph and 'push' and 'hold' buttons that permit temporarily slowing down or speeding up the beat clock. It can also transmit MIDI Machine Control and MIDI beat clock, and slave to external beat clock sources such as other Roland grooveboxes.
The MIDI protocol features a MIDI beat clock. MIDI beat clock also works with 24 ticks per quarter note. MIDI timecode is used for more general timecode synchronization applications. Analog clock signals are equivalent to the clock signal at pin 3 of DIN sync interface. The clock rate is usually higher than the DIN sync's rate.
A sequencer can drive a MIDI system with its internal clock, but when a system contains multiple sequencers, they must synchronize to a common clock. MIDI timecode (MTC), developed by Digidesign, [122] implements SysEx messages [123] developed specifically for timing purposes, and can translate to and from the SMPTE timecode standard.

Clock signal and legend. In electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat) [1] is an electronic logic signal (voltage or current) which oscillates between a high and a low state at a constant frequency and is used like a metronome to synchronize actions of digital circuits.
The main MIDI standard specifies abstract communications protocol for synthesizers, dealing with how to transmit note numbers and controllers, but not what they mean.More standards were created afterwards to state correspondence of particular sounds and sound effects to particular numbers transmitted.
MIDI time code (MTC) embeds the same timing information as standard SMPTE timecode as a series of small 'quarter-frame' MIDI messages. There is no provision for the user bits in the standard MIDI time code messages, and SysEx messages are used to carry this information instead. The quarter-frame messages are transmitted in a sequence of eight ...
