Channeling inspiration from the Roland SYSTEM-100m's 150 and 165 modules, the SYS-555 is a five-in-one powerhouse that brings core utility functions to your modular setup, but with some new and interesting twists. The SYS-555 contains both traditional and non-traditional modulation sources applicable to any imaginable configuration or setup. With ring modulation, versatile sample and hold with seven waveforms and internal LPF, pink and white noise modes, LFO with internal ENV and VCA, and two CV controlled portamento circuits, your tonal shaping and modulation options are near infinite.
