The Noise Engineering Sinc Bucina (Silver) is a 4HP Resonant Low-Pass Gate Eurorack Module which combines Filter, Envelope and VCA. The controller-less 6-12dB Low-Pass Filter is directly addressed by the Envelope and can be switched to LPG. In VCA Mode, it can generate the popular Buchla Bongos. The Attack/Release Envelope has its own CV Output and can be used for Modulation outside the Sinc Bucina.
