This System-100M 190 Enclosure is fully functional and in great condition.

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, this M-190 holds 3 modules.
