Roland MTR-100
The Roland MC-4 MicroComposer was an early microprocessor-based music sequencer released by Roland Corporation. It could be programmed using the ten key numeric keyboard or a synthesizer keyboard using the keyboard's control voltage and gate outputs. It was released in 1981 with a list price of US$3,295 (¥430,000 JPY) and was the successor to the MC-8, which in 1977 was the first microprocessor-based digital sequencer. Like its predecessor, the MC-4 is a polyphonic CV/Gate sequencer. Chris CarterROLAND MC8 MICROCOMPOSER ''Sound on Sound'', Vol.12, No.5, March 1997 Information This sequencer was released before the advent of MIDI, and viewed by some composers to have more accurate timing. The MC-4 has an output patchbay to the right of the control panel, allowing you to patch the MC-4 to a synthesizer using 3.5mm patch cords. There are four channels of outputs containing CV-1, CV-2, Gate and MPX (multiplex) to control four separate synthesizers.page 1, Roland Microcomposer ...

Delete Key
The delete key is a key on most computer keyboards which is typically used to delete either (in text mode) the character ahead of or beneath the cursor, or (in GUI mode) the currently-selected object. The key is sometimes referred to as the "forward delete" key. This is because the backspace key also deletes characters, but to the left of the cursor. On many keyboards, such as most Apple keyboards, the key with the backspace function is also labelled "delete". Position and labeling on keyboards The key appears on English-language IBM-compatible PC keyboards labeled as or , sometimes accompanied by a crossed-out right-arrow symbol. A dedicated symbol for "delete" exists as U+2326 ⌦ but its use as a keyboard label is not universal. However, sometimes the key labelled performs the Backspace function instead, for example on some Apple keyboards. In other cases, the Delete key is in its original IBM notebook position of above and to the right of the Backspace key. Many lapt ...

Digital Data
Digital data, in information theory and information systems, is information represented as a string of discrete symbols each of which can take on one of only a finite number of values from some alphabet, such as letters or digits. An example is a text document, which consists of a string of alphanumeric characters . The most common form of digital data in modern information systems is ''binary data'', which is represented by a string of binary digits (bits) each of which can have one of two values, either 0 or 1. Digital data can be contrasted with ''analog data'', which is represented by a value from a continuous range of real numbers. Analog data is transmitted by an analog signal, which not only takes on continuous values, but can vary continuously with time, a continuous real-valued function of time. An example is the air pressure variation in a sound wave. The word ''digital'' comes from the same source as the words digit and ''digitus'' (the Latin word for ''finger'' ...

Roland OP-8
The Roland OP-8 interface was designed to control Roland polyphonic synthesizers that were equipped with a DCB (Digital Control Bus) interface via the Roland MC-4 Microcomposer.Roland OP-8 Operation Manual The OP-8 and synthesizer were connected together using a DCB cable. The OP-8 and MC-4 Microcomposer were then patched together using patchcords via each of their patchbays. The transpose control on the OP-8 was able to transpose the synthesizer up or down by one octave. DCB Equipped Synthesizers * Roland Jupiter 8 The Jupiter 8 needed minor changes in its circuit for setting up with the OP-8. This work was carried out by Roland. * Roland Juno 60 When using the OP-8 with a Roland Juno 60 The Roland Juno-60 is an analog synthesizer manufactured by the Roland Corporation between 1982 and 1984. It followed the Juno-6, an almost identical synthesizer released months earlier. The Juno synthesizers introduced Roland's digitally control ... the connection and operation were extremely e ...

Compact Cassette
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge and reel ...

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]   |

DIN Connector
The DIN connector is an electrical connector that was standardized by the ' (DIN), the German Institute for Standards, in the early 1970s. The male DIN connectors (plugs) feature a 13.2 mm diameter metal shield with a notch that limits the orientation in which plug and socket can mate. The range of DIN connectors, different only in the configuration of the pins, have been standardized as DIN 41524 / IEC/DIN EN 60130-9 (3-pin at 90° and 5-pin at 45°); DIN 45322 (5-pin and 6-pin at 60°); DIN 45329 / IEC/DIN EN 60130–9 (7-pin at 45°); and DIN 45326 / IEC/DIN EN 60130-9 (8-pin at 45°). In consumer electronics, the term "DIN connector" identifies types of cylindrical connectors that the German Institute for Standards (DIN) had initially standardised for analog audio signals. Some DIN connectors have been used in analog video applications, for power connections, and for digital interfaces, such as the MIDI (DIN 41524), the IBM PC keyboard and the IBM AT keyboard connect ...

Staccato
Staccato (; Italian for "detached") is a form of musical articulation. In modern notation, it signifies a note of shortened duration, separated from the note that may follow by silence. It has been described by theorists and has appeared in music since at least 1676. Notation In 20th-century music, a dot placed above or below a note indicates that it should be played staccato, and a wedge is used for the more emphatic staccatissimo. However, before 1850, dots, dashes, and wedges were all likely to have the same meaning, even though some theorists from as early as the 1750s distinguished different degrees of staccato through the use of dots and dashes, with the dash indicating a shorter, sharper note, and the dot a longer, lighter one. A number of signs came to be used in the late 19th and early 20th centuries to discriminate more subtle nuances of staccato. These signs involve various combinations of dots, vertical and horizontal dashes, vertical and horizontal wedges, and t ...

Legato
In music performance and notation, legato (; Italian for "tied together"; French ''lié''; German ''gebunden'') indicates that musical notes are played or sung smoothly and connected. That is, the player makes a transition from note to note with no intervening silence. Legato technique is required for slurred performance, but unlike slurring (as that term is interpreted for some instruments), legato does not forbid re- articulation. Standard notation indicates legato either with the word ''legato'', or by a slur (a curved line) under notes that form one legato group. Legato, like staccato, is a kind of articulation. There is an intermediate articulation called either ''mezzo staccato'' or ''non-legato'' (sometimes referred to as ''portato''). Classical string instruments In music for Classical string instruments, legato is an articulation that often refers to notes played with a full bow, and played with the shortest silence, often barely perceptible, between notes. The play ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pitch (music)
Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Musical Note
In music, a note is the representation of a musical sound. Notes can represent the Pitch (music), pitch and Duration (music), duration of a sound in musical notation. A note can also represent a pitch class. Notes are the building blocks of much written music: musical analysis#Discretization, discretizations of musical phenomena that facilitate performance, comprehension, and musical analysis, analysis. The term ''note'' can be used in both generic and specific senses: one might say either "the piece 'Happy Birthday to You' begins with two notes having the same pitch", or "the piece begins with two repetitions of the same note". In the former case, one uses ''note'' to refer to a specific musical event; in the latter, one uses the term to refer to a class of events sharing the same pitch. (See also: Key signature names and translations.) Two notes with fundamental frequency, fundamental frequencies in a ratio equal to any integer power of two (e.g., half, twice, or four times ...
