Roland MKS-70 Super JX

Roland MKS-70 Image

The MKS-70 is an identical rackmount version of the JX-10 synthesizer. Released in 1986 it combines two individual JX-8P synth engines for an outstanding warm and analog sound which is used in many modern studios all over the world. It comes with onboard effects like Chorus and Delay and offers a wider range of programming using the optional PG-800 Programmer. This programmer is highly recommended for those who will be programming unique sounds since editing from the rack-face itself is cumbersome and tedious. The MKS-70 has a "chase-play" function which allows programmable delayed repeats of voices from either of its tone modules. The chorus is either off, slow or fast. It is used by Überzone, Vangelis, Astral Projection and Josh Wink.

My favourite synth of all time, period. Capable of convincing recreations of acoustic instruments, and any synth sound you can think of. Editing tones is straight forward, patch editing requires a bit of forward thinking. A PG-800 is pretty useful, but I use my Mackie C4 these days.

Great sound. Finally one peace of gear that doesn't make me sick after listening to it for more than 15 minutes. Great strings, thick bass, very good sound of chorused piano even. Will not seperate from it! Got it for 300$ with memory card (wich is useful for live). Lucky I was. Get it if you can, you will not regret it.

This was one of the first I ever had. No pulse with mod, but a solid fat pad/ string maker. The bass sounds can be good. Mines been in the shop twice which is how I discovered it only has square wave DCO's and it shapes them down to saw waves. Super nice filters. not that bad to program using the front panel. LFO's are a little wonky for those BOC vibrato type sounds, but sweep the filter well. I'd like to hear somebody make the "cross mod" useful. I got mine for 350usd in 95'. If you can find a deal on the the MKS80 i'd get it instead but, this with an MKS50 (which will cost soooo much less) and you're covered.

for biiiig warm thick pads and strings, this is one of the best analog synths ever!
super-smooth, and it's so burly that it's back panel it sticks out 3" behind my rack. serious hardware, kids.
i got mine in very good condition w/ pg-800 for 600USD. One of the best deals on vintage synth today, and highly recommended over the keyboard version (JX10) which has build and keybed issues.

It was actually released in 1986.
More famous Super JX users were Jazz giants Lyle Mays (Pat Matheny) and Russel Ferrante (Yellowjackets), who made the JX's brass sound his signature sound.
Nik Kershaw used the JX a lot on his Radio Musicola and The Works albums.
