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.

Had this for about a month now, paid a lot for it but it's in good nick and am in love with the sound. Not really a synth for power leads but great for anything else - pads, keys, strings, brass, bass. Really reminds me that no matter how good digital/computer emulation gets these old synths just seems to be warmer and deeper (especially the strings and basses). Got a JX-8P so this is just like having 2 of them in one box. Bit of a pain to program so you need a PC/Mac program like Unisyn or get the PG controller. Limited by the number of user preset you can have (so digital is good at something!) but that just concentrates the mind.
