ROLAND MKS80 Analog Synthesizer

ABOUT the classic Ju8, well known, so maybe just to say, it sounds a bit "aggressive" compared to us-synths of that time. the mks80 is the Jupiter 8 in a rack. it has no 2 pole filter mode but Crossmodulation can be controlled by ENV1

DETAILS quite fast LFO (about 64Hz), cool sync in both directions. Xmod modulation possible by ENV1. It adds dynamics to the Jupiter sound which is only available in the Rack (mks80). HARDWARE INFO: Filter? Curtis? Roland? Thats a common mistake. But there is NO CEM filters in any of the MKS revisions. The CEM rev. has only CEM VCO and VCA even the ju8 has no curtis filters.. same for the ju6.. Both revisions uses 2 CEM3360 _DUAL_ VCA per voiceboard for Crossmodulation- The older revision usesr IR309 filter like in JP4, JP8, Juno60 etc. The newer MKS uses IR305 which is both VCF and VCA. like in Juno1/2, JX-10 etc. So it is right as follows (I will remove the wrong ones soon): MKS-80 (racked jupiter8) MKS80 used 8 x IR3RO5 ..to Serial <#511800:-- 16 CEM3340 VCO 8 CEM3360 Dual VCA 12 IR-3R09 VCF MKS80 serial >511800:-- 16 IR-3R03 Roland VCO 4 CEM3360 Dual VCA 8 IR-3R05 VCF/VCA

SOUND everything classic: pads, basses and sweeps

VERSION Rack: MKS80, + Programmer PG80 (no 2pole mode but Xmod Modulation by ENV1 instead). Most Ju8 had no Midi, some (later models) had DCB, there are DCB to midi interfaces still available. the Jupiter 6 has multimode filters but less voices and not as fat as the Ju8 but also Xmod modulation by Env and all wave can sound simultaneously. IMPORTANT: the earlier version sounds a bit better, after a changed it was more stable (tuning) - mks80 vs. mks80: as said there are 2 versions: the earlier curtis version is a bit thicker in sound (till ser.511799), the later "roland" version (not that BOTH are roland filters, there is a myth around that there has been a "curtis" version, in fact it's only another structure with curtis chips and they ALL used the roland filter chip..the later one is more stable since it is the OSCs (thats the thing that changed), but to my ears the mks80 still sounds more fat than the jupiter6, still.. the interesting thing here that it's no difference in the filter chips, there are no "curtis filters" used on all mks80, but the rest had changed.. want OS Version? hold auto tune + write while power on..(but I have no idea what is cool here, a newer version is 5.0 - "roland" chips myth version..)
