This is a compact 6HP analog multimode filter inspired by the classic Korg MS-20, featuring aggressive resonance, adjustable drive, and four simultaneous filter outputs.

Based on René Schmitz's MS-20 filter circuit, Kilter combines versatile sound shaping with extensive voltage control in a compact Eurorack format.
