"The MKS-30 is the rack version of the Roland JX-3P keyboard and the GR-700 Guitar Synthesizer. Sounds like a Juno Series Syntheszer, but much better since it has 2 oscillators with sync and ring modulation, as well as PWM. Excellent Filters plus, one of the best features, just like the Juno 60, 106 and MKS-7, is the pitch bends have a very analog, elastic kind of stretching quality to them, sort of like a rubber band being plucked and stretched. Not many DCO based Analog Synths I've heard do this, except for the Juno's. In fact I recently had a MKS-7(rack of Juno106), and I was surprised by how close the oscillators sound to the MKS30 's. Except you get two of them that can sync and be ring modulated. Plus it has a nice analog chorus circuit built-in for stereo effects.

Some people say it's got a digital sound, but I compared this to the MKS-7, which everybody says is effectively a racked Juno-106. The MKS-30 is just as analog sounding with a remarkably punchy, and pure musical character, especially on those pitch-bends. A few years ago, I was planning to buy a Access Virus C, and this MKS-30 was sitting close by in Guitar Center. After trying both of them out side by side, I ended spending my money on this one. The Virus is great, but compared to this, it's sound is clearly digital. At the time I was looking for that deep analog quality. This synth has that. It's also functionally better than it's keyboard counterpart, the JX3P. It has a better implementation of MIDI with velocity. It's easily programmed from the front panel, however their isn't any sysex that can be accessed by an editor. However, the Roland PG-200 programmer/knob box can be plugged into it, or there is a 3rd party ROM upgrade that can be purchased for around $100(last time I checked) that gives you full sysex, CC control over every parameter. Here's a link to that information."
