The System 100M is Roland`s analog modular synthesizer. It was based originally on the semi modular System 100 but with more features that put this system ahead. The System 100m offers over 20 modular components to choose from to build your own modular setup.
The 112 M is a dual VCO with 3CV ins and 2 outs. The 121 is dual VCF with low pass and high pass filters with a 24db/oct slope. The 130 is a dual VCA with linear exponentional switch. The 140 consists of dual Envelope and LFO and the 150 consists of Ring Mod, Noise, Sample and Hold and a LFO.
It also comes with 181 keyboard which is a 49 note keyboard with portamento and bender.
A very rare piece of item from Roland.
