I got one of these off eBay. It is fitted with 2 modules. For some reason it is quite unstable when both modules are inserted but using only 1 module is working perfectly. I don't have any of the problems reported by some users around in the net. I find it very nice sounding, very creative, there are many routings options. It would be great to have an editor or to be able to use an external controller to control at least the most important parameters. Even if the menus are very logically organised, nevertheless the complexity of this instrument makes it very difficult to program using just 2 knobs, 2 buttons and a relatively small display. Anyway I think it can be a good buy if you are looking for a very versatile, wondeful sounding 8-voice analog sinth. Not so good for bass and percussion, very good for pads, brass, various keyboard sounds, ambient drones. For me it is the perfect companion for my Moog Voyager and Yamaha TX-802.

I realize I can think of some synths that one might argue is more complex than the msr2, but it's more than complex enough, to put it mildly.

I can't think of a more complex and modular-like analog racksynth. And it's only 1u! The amount and variety of modulators is stunning, even with no arp or sequencer onboard. 10! simultaneous modulation sources and destinations, and more or less every parameter is available either as source or destination. 7 band onboard eq. Onboard mixer with panning. Multitimbral. External sound can be processed through the vast synth engine, in 12 or 24 db, even in stereo!!!! My god! An insanely comprehensive and elaborate synth. A patient programmers dream. Can't wait to actually hear it! LOL! -: )

Comes with more than 200 superb sounding Oberheim alike presets!
