Roland System-500 505

Roland System 500 505 is a filter module for modular synthesizers in Eurorack format. The module is inspired by the filter section of the classic synth Roland SH-5. Unlike the traditional ladder filter design, the SH-5's filters did not simply cut off the bass, but transformed it into a resonant growl effect. This circuit also has the module. In addition, integrated VCAs, CV-controlled cutoff frequency and resonance as well as switchable outputs.

Roland System-500 is a completely analog recreation of the Roland System-100M modular synthesizer and thus the modern reissue of a world-famous legend.
