A very fat sounding synth. Back in the 1970s, Roland launched the SYSTEM 100, SYSTEM 100M, and the now almost mythical SYSTEM 700. These modular and semi-modular synthesizers are heralded to this day for their flexibility and character of sound. A major player in the modular synth market, it competed against monsters like the Moog Modulars and the ARP 2500 & 2600. The System 700 was a great big modular analog synthesizer system from Roland. Incredible flexibility and great sound and design.
