what is the rate of midi clock in ppqn
24 ppqn
title: MIDI beat clock text: MIDI beat clock MIDI beat clock (also known as MIDI timing 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. It is not MIDI timecode. Unlike MIDI timecode, the MIDI beat clock is tempo-dependent. Clock events are sent at a rate of 24 ppqn (pulses per quarter note). Those pulses are used to maintain a synchronized tempo for synthesizers that have BPM-dependent voices and also for arpeggiator synchronization. Location information can be specified using MIDI Song Position Pointer (SPP, title: Pulses per quarter note text: Pulses per quarter note PPQN (Pulses Per Quarter Note, also known as PPQ, Pulses Per Quarter and TPQN, Ticks Per Quarter Note) is the smallest unit of time used for sequencing note and automation events, both by step sequencers and in the MIDI standard. Most MIDI sequencers allow the number of PPQ to be varied for more or less temporal resolution depending on the needs of the performer. If there are too few PPQ any performance recorded into the MIDI sequencer may sound artificial (being quantised by the Pulse rate) or lose subtle variations in timing that gives music a title: RTP-MIDI text: rate. The timing accuracy of all MIDI events is then 100 microseconds for these implementations. Sender and receiver clocks are synchronized when the session is initiated, and they are kept synchronized during the whole session period by the regular synchronization cycles, controlled by the session initiators. This mechanism has the capability to compensate for any latency, from a few hundreds of microseconds, as seen on LAN applications, to seconds. It can compensate for the latency introduced by the Internet for example, allowing real-time execution of music pieces. This mechanism is however mainly designed for pre-recorded MIDI streams, like the one title: MIDI timecode text: exclusive" byte. After a jump, the time clock stops until the first following quarter-frame message is received. When the time is running continuously, the 32-bit time code is broken into 8 4-bit pieces, and one piece is transmitted each quarter frame. I.e. 96—120 times per second, depending on the frame rate. Since it takes eight quarter frames for a complete time code message, the complete SMPTE time is updated every two frames. A quarter-frame messages consists of a status byte of 0xF1, followed by a single 7-bit data value: 3 bits to identify the piece, and 4 bits of partial title: MIDI text: and is able to translate to and from the SMPTE time code standard. MIDI Clock is based on tempo, but SMPTE time code is based on frames per second, and is independent of tempo. MTC, like SMPTE code, includes position information, and can adjust itself if a timing pulse is lost. MIDI interfaces such as Mark of the Unicorn's MIDI Timepiece can convert SMPTE code to MTC. MIDI Machine Control (MMC) consists of a set of SysEx commands that operate the transport controls of hardware recording devices. MMC lets a sequencer send "Start", "Stop", and "Record" commands to a connected
