Overview
The Roland System 100, released in 1975, was a modular synthesizer system designed for educational and professional use. This comprehensive system included a keyboard, expander modules, and a sequencer that could be configured in various combinations.
The System 100 used Roland's early analog circuitry, offering rich, characterful sounds distinct from Moog and ARP instruments. The modular format allowed flexible signal routing and experimentation with synthesis techniques.
The System 100 is rare today, with complete systems commanding premium prices. It represents Roland's early entry into the modular synthesizer market before the company shifted to integrated keyboards.
