Summary: The rackmount midi version of the Roland Jupiter-6 and Jupiter-8. Sonically not always as impressive as the Jupiters, but with more programming flexibility and impressive midi implementation (including velocity sensitivity and sysex control of all parameters). Synth: Roland MKS-80 Super Jupiter. Review by: Mike Perkowitz (map@cs.washington.edu) Years Made: ? through ? Polyphony: 8 Multitimbral: bitimbral MIDI: yes, including sysex send/receive on all programmable parameters Other external control: a knobs 'n' sliders programmer is available Patch storage: 128 internal, more on a cartridge, dump via midi sysex Voice architecture: VCO: 2 VCOs, with standard waveforms, pulsewidth, extensive cross-mod LFO: rate, delay, waveforms (incl random) VCF: HPF LPF with freq, resonance, env mod, kbd mod, lfo mod ENV: 2 ADSR Modulation routings are more extensive than either of the Jupiters, allowing many modulations to be inverted at the destination Patches can be split/layered/used bitimbrally in performance memories Sequencer/Arpeggiator: none Keyboard/rack: 2-unit rackmount Accessories: MPG-80 programmer. has pots/buttons for every parameter, rackmount or tabletop. Related synths/gear: Jupiter-8: thicker sound than the Jupiter-6 or MKS-80. Big monster keyboard, no MIDI (later models have DCB; can be converted to MIDI) less control and modulation than either the Jupiter-6 or MKS-80 Jupiter-6: sounds very similar to the MKS-80 except with a single multimode (low-pass, high-pass, band-pass) resonant filter. Like the JP-8, also has an arpeggiator. minimal midi, but is bitimbral. MKS-70: actually a rackmount version of the JX-10. Perhaps comparable to the MKS-80 in programming power, but a very different sound. Comments: good midi implementation, sysex control of params very nice. In many ways the apex of the Jupiter line, but some people prefer the sound of the older units.
