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 ...

Polyphonic
Polyphony ( ) is a type of musical texture consisting of two or more simultaneous lines of independent melody, as opposed to a musical texture with just one voice, monophony, or a texture with one dominant melodic voice accompanied by chords, homophony. Within the context of the Western musical tradition, the term ''polyphony'' is usually used to refer to music of the late Middle Ages and Renaissance. Baroque forms such as fugue, which might be called polyphonic, are usually described instead as contrapuntal. Also, as opposed to the ''species'' terminology of counterpoint, polyphony was generally either "pitch-against-pitch" / "point-against-point" or "sustained-pitch" in one part with melismas of varying lengths in another. In all cases the conception was probably what Margaret Bent (1999) calls "dyadic counterpoint", with each part being written generally against one other part, with all parts modified if needed in the end. This point-against-point conception is opposed to "su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Control Bus
DCB (Digital Control Bus, Digital Connection Bus or Digital Communication Bus in some sources) was a proprietary data interchange interface by Roland Corporation, developed in 1981 and introduced in 1982 in their Roland Juno-60 and Roland Jupiter-8 products. DCB functions were basically the same as MIDI, but unlike MIDI (which is capable of transmitting a wide array of information), DCB could provide note on/off, program change and VCF/VCA control only. DCB-to-MIDI adapters were produced for a number of early Roland products. The DCB interface was made in 2 variants, the earlier one used 20-pin sockets and cables, later switching to the 14-pin Amphenol DDK connector vaguely resembling a parallel port. Supporting equipment DCB was quickly replaced by MIDI in the early 1980s which Roland helped co-develop with Sequential Circuits. The only DCB-equipped instruments produced were the Roland Jupiter-8 and JUNO-60; Roland produced at least two DCB sequencers, the JSQ-60 and the ...

Roland MC-4 Microcomposer
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 Japanese yen, JPY) and was the successor to the Roland MC-8 Microcomposer, MC-8, which in 1977 was the first microprocessor-based digital sequencer. Like its predecessor, the MC-4 is a Polyphony and monophony in instruments, polyphonic CV/Gate sequencer.Chris Carter (British musician), 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 (music), 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 o ...

Roland Jupiter 8
The Jupiter-8, or JP-8, is an eight-voice polyphonic analog subtractive synthesizer introduced by Roland Corporation in early 1981. The Jupiter-8 was Roland's flagship synthesizer for the first half of the 1980s. Approximately 3300 units have been produced. Although it lacked the soon-to-be standard of MIDI control, later production series of the Jupiter-8 did include Roland's proprietary DCB interface. The instrument had many advanced features for its time, including the ability to split the keyboard into two zones, with separate patches active on each zone. Two years after the release of the Jupiter-8, Roland released the more affordable Jupiter-6 synthesizer with built-in MIDI control but an otherwise slightly reduced set of features. In 2011, three decades after the release of the original Jupiter series, Roland released the fully digital Jupiter-80 and Jupiter-50 synthesizers as successors to the 1980s originals. They were in turn succeeded by the Jupiter-X and Jupite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 controlled oscillators, allowing for greatly improved tuning stability over its competitors. The Juno-6 and Juno-60 were introduced as low-cost alternatives to polyphonic synths such as the Sequential Circuits Prophet-5 and Roland's own Jupiter-8. Its built-in chorus effect was designed to make up for the weaker sound of its single oscillator, and it went on to become its signature effect. The Juno-60 had an immediate impact in 1980s pop music, being used on hits such as "Take On Me" by A-ha and " Time After Time" by Cyndi Lauper. The Juno-60 continued to be popular in the 1990s, being used by house and techno artists. It experienced a resurgence in the 2000s and beyond, gaining popularity amongst modern pop, indie and synthwave artists. It has ...
