Multimode filter and rectifier
The MSK~009 is a multimode voltage-controlled filter for Eurorack modular synthesizers, with a unique inductor-based integrator section.
Simultaneous low-pass, band-pass, and high-pass outputs, and a full-wave rectifier input, provide a wide range of sonic possibilities. Non-venomous.
