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.
