Bubblesound SEM20st: The Soul of Vintage Filtering
The SEM20st is a compact version of the classic SEM-inspired filter, offering the smooth and airy response that makes Oberheim-style circuits so desirable. The module features a "State" control that allows you to transition smoothly from Low Pass to High Pass, passing through a deeply musical Notch filter in the center. Because the SEM architecture is state-variable, it offers a wider, more open soundstage compared to traditional transistor ladders. Housed behind a premium black-anodized faceplate, it is an essential VCF for those seeking rich, vintage-inflected textures.
Key Features:
-
12dB Multi-mode Architecture: Classic state-variable design for versatile sound sculpting.
