it DCB capability. The Jupiter-6 was released 2 years after the JP-8 and was an attempt at more affordable version of Roland's flagship. It features a similar voice architecture and appearance. It stored fewer patches, and had six voices. In order to make it cheaper to manufacture, a move towards integrated circuits (Curtis) was made, to replace discrete circuits used in JP-8's oscillators and amplifiers. The JP-6 is built using CEM3340 chip for its oscillators, and CEM3360 for its voltage controlled amplifiers. These changes imparted a change in sonic character, meaning that the JP-6 is not simply a less-expensive version of the JP-8, but an instrument with its own distinct sound. Additionally, the Jupiter-6 features a true multimode resonant filter, built-in MIDI, unison detune function and the ability to activate multiple waveforms on a single oscillator. The Roland MKS-80 Super Jupiter is a MIDI-controlled, rack-mountable sound module with a similar voice architecture to the Jupiter-8. However, its first released incarnation in 1984 (revision 3 and 4) used hardware similar to its predecessor, the Jupiter-6 (which had a combination of Curtis VCO and VCA chips combined with Roland's own proprietary filters). In 1985, Roland released another revision of the MKS-80, known as Rev 5, which used different VCO, VCA and filter circuits. As a result, the MKS-80 Rev 5 can sound a bit different from its predecessors. The Rev 5 filter was also used in the JX-8P, JX-10 and MKS-70 synthesizers. At the 2007 NAMM show, French music software manufacturer Arturia announced, and subsequently released a software Jupiter-8 called Jupiter-8V. A 2007 review in Sound on Sound stated, "8V sounds much like Jupiter 8, but does a zillion things that the original could not." The Jupiter-8V is available in VST, AU, RTAS and AAX plugin formats. The Roland VariOS provides a mildly successful digital approximation of the Jupiter-8 using its "Varios-8" software. In 2011, Roland released the JUPITER-80 and JUPITER-50, which inherit much of the visual style of the Jupiter-8 and include Roland's SuperNATURAL, an extensive synthesis engine that includes virtual analog synthesis akin to a digital recreation of earlier Roland analog synths, as well as PCM-based recreations of purely digital synths by the company and acoustic modelling of real instruments. Emulations of the original Jupiter-8 sounds were later released as a software instrument for both keyboards on Roland Axial as part of the Synth Legends series. On October 1, 2015,
