Roland System 100m
The System 100m is Roland's contribution to professional analog modular synthesis. It was based on the more limited, semi-modular System 100, but is several steps of ahead of its predecessor. The System 100m offers over 20 modular components to pick and choose to design a custom modular set-up. The Main unit is the M-110 which has a single VCO oscillator, VCF, and VCA section. You can then build upon this system adding any number and configurations of the various other modules which include dual VCOs, ring modulators, dual VCFs, eq, dual VCAs, dual envelopes, LFOs, various effects, mixers, sequencers, and control interfaces including 3 different keyboard controllers.
Modules are assembled into racks. The System 100m has 3 rack sizes, the M-190 holds 3 modules, the M-191 and M-191J hold 5 modules. Each rack provides the necessary 8-pin DIN power connectors and internal CV/gate connections between the modules. You still need to do some external patching, however, to send your signal through the modules of your choice to create any sounds. As for sounds, the System is basically monophonic, unless you get several racks of them for lots and lots of money! Its sound is not as warm as the System 100 before it, but it offers much more capability, as seen in Hans Zimmer's system below!

Hans Zimmer's massive System 100m, image and info courtesy of Kevin Lightner. "It features 58 VCOs, 37 VCFs, 32 ENVs, 12 VC Phase shifters, 9 Sequencers, 1 Remote controlled 4-space rack-mount power supply (25' away.), and 24 Trunk lines go to his large Moog synth across the room. The unit can link the "Keyboard" inputs for all the modules, and with this feature, all VCO's can track one input with only one patch cord. The unit was built into 6 flight cases on casters with removable front and rear covers, then later encased in wood and built into his studio. "----Kevin Lightner
System 100's have been used by Orbital, Hans Zimmer, Vince Clarke, Depeche Mode, Heaven 17, Freddy Fresh, Luke Vibert, Meat Beat Manifesto, Electronic Dream Planet, Jamiroquai, Human League, and Peter Howell of the BBC Radiophonic Workshop.

You are right there so many synths out there that sound fatter..but they don't have
anything unique soundwise they all sound like each other. What the 100M has IS CHARACTER! Meaning that they have a UNIQUE timbre, sound...So, if you love the
sound of the 100M you don't buy anything else...If Vince Clark swears by them then who are you to differ? So shut it!

Ryk also did a perfect reproduction of the 182 sequencer with 16 steps, I bought the only one he ever did from him then sold it to a german guy... BIIIIIG MISTAKE! :-(
You are one of those wankers who never touched this instrument and claim to know
that it has a tiny sound...Watch my videos on the links page of my site redoutput in the next month or so (my studio is being wired up as we speak) and tell me which bit is tiny sounding. And hey, I also have the Digisound 80s VCOs and a multimode filter, plys SH-5, Moog Source, System 100, etc, etc...so I KNOW what is fat sounding and what is not! I have 4 VCOs and the same number of VCFs, VCA,s EG and LFOs plus Ryk's 185 sequencer!
