Pulses Per Quarter Note
In a music sequencer and MIDI clock, pulses per quarter note (PPQN), also known as pulses per quarter (PPQ), and ticks per quarter note (TPQN), is the smallest unit of time used for sequencing note and automation events. If the resolution is too low (too few PPQN), the performance recorded into the sequencer may sound artificial (being quantised by the pulse rate), losing all the subtle variations in timing that give the music a "human" feeling. Purposefully quantised music can have resolutions as low as 24 (the standard for Sync24 and MIDI, which allows triplets, and swinging by counting alternate numbers of clock ticks) or even 4 PPQN (which has only one clock pulse per 16th note). At the other end of the spectrum, modern computer-based MIDI sequencers designed to capture more nuance may use 960 PPQN and beyond. This resolution is a measure of time relative to tempo since the tempo defines the length of a quarter note and so the duration of each pulse. The resulting PPQN per ...

Music Sequencer
A music sequencer (or audio sequencer or simply sequencer) is a device or application software that can record, edit, or play back music, by handling note and performance information in several forms, typically CV/Gate, MIDI, or Open Sound Control (OSC), and possibly audio and automation data for DAWs and plug-ins. On WhatIs.com of TechTarget (whatis.techtarget.com), an author seems to define a term "Sequencer" as an abbreviation of "MIDI sequencer". * Note: an example of section title containing "''Audio Sequencer''" Overview Modern sequencers The advent of Musical Instrument Digital Interface (MIDI) and the Atari ST home computer in the 1980s gave programmers the opportunity to design software that could more easily record and play back sequences of notes played or programmed by a musician. This software also improved on the quality of the earlier sequencers which tended to be mechanical sounding and were only able to play back notes of exactly equal duration. Sof ...

MIDI Clock
{{No footnotes, date=January 2020 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. Those pulses are used to maintain a synchronized tempo for synthesizers that have BPM-dependent voices and also for arpeggiator synchronization. MIDI beat clock differs from MIDI timecode in that MIDI beat clock is tempo-dependent. Location information can be specified using MIDI Song Position Pointer (SPP, see below), although many simple MIDI devices ignore this message. Messages MIDI beat clock defines the following real-time messages: * clock (decimal 248, hex 0xF8) * start (decimal 250, hex 0xFA) * continue (decimal 251, hex 0xFB) * stop (decimal 252, hex 0xFC) MIDI also specifies a System Common message called Song Position Pointer (SPP). SPP can be used in conjunction with the above rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sync24
DIN sync, also called Sync24, is a synchronization interface for electronic musical instruments. It was introduced in the early 1980s by Roland Corporation and has been superseded by MIDI. Definition and history DIN sync was introduced in the early 1980s by Roland Corporation for the synchronization of music sequencers, drum machines, arpeggiators and similar devices. It was superseded by MIDI, in the mid to late 1980s. DIN sync consists of two signals, clock (tempo) and run/stop. Both signals are TTL compatible, meaning the low state is 0 V and the high state is about +5 V. The clock signal is a low-frequency pulse wave suggesting the tempo. Instead of measuring the waveform's frequency, the machine receiving the signal merely has to count the number of pulses to work out when to increment its position in the music. Roland equipment uses 24 pulses per quarter note, known as Sync24. Therefore, a Roland-compatible device playing sixteenth notes would have to adv ...

Tempo
In musical terminology, tempo (Italian, 'time'; plural ''tempos'', or ''tempi'' from the Italian plural) is the speed or pace of a given piece. In classical music, tempo is typically indicated with an instruction at the start of a piece (often using conventional Italian terms) and is usually measured in beats per minute (or bpm). In modern classical compositions, a "metronome mark" in beats per minute may supplement or replace the normal tempo marking, while in modern genres like electronic dance music, tempo will typically simply be stated in BPM. Tempo may be separated from articulation and meter, or these aspects may be indicated along with tempo, all contributing to the overall texture. While the ability to hold a steady tempo is a vital skill for a musical performer, tempo is changeable. Depending on the genre of a piece of music and the performers' interpretation, a piece may be played with slight tempo rubato or drastic variances. In ensembles, the tempo is often ind ...

Quarter Note
A quarter note (American) or crotchet ( ) (British) is a note (music), musical note played for one quarter of the duration of a whole note (or semibreve). Quarter notes are notated with a filled-in oval note head and a straight, flagless stem (music), stem. The stem usually points upwards if it is below the middle line of the musical staff, staff, and downwards if it is on or above the middle line. An upward stem is placed on the right side of the notehead, a downward stem is placed on the left (see image). The Unicode symbol is U+2669 (♩). A quarter rest (music), rest (or crotchet rest) denotes a silence of the same duration as a quarter note. It typically appears as the symbol , or occasionally, as the older symbol .''Rudiments and Theory of Music'' Associated Board of the Royal Schools of Music, London 1958. I,33 and III,25.
