The SALLEN KEY is a tribute to the legendary MS-20 filter.

The filter circuit is composed of a 2 Pole Low Pass and a 1 Pole High Pass, and unlike the original Korg design,  this module features a crossfader allowing you to blend the Low Pass and High Pass filters to create complex filtering.

Another unique feature of the SALLEN KEY is its non-linear feedback path. This design avoids clipping when self-oscillating, which gives the sound a special character. Since SALLEN KEY can self-oscillate, the filter can also be used as a VCO. Tracking is accurate across 6 octaves.
