The BF-22 VCF is a dual Hi/Low-pass filter inspired by the Sallen-Key filter from the early MS-20.

DISCLAIMER: This filter brings to your modular system the character of early MS-20 sound: Kick-ass-rocking-dirty screams! It inherited not only it’s amazing sound, also MS-20 noise floor. If noise floor is an issue for you, this might not be your filter.
