Late KORG MS20 Filter inspired

SALLEN-KEY reproduce the architecture of the late KORG MS20 filter.
It’s composed of a –12dB/oct low pass and a -6dB/oct high pass,
Unlike the original, you can select/mix each filter type with the dedicate knob.
Like the original MS20, Sallen Key offer a non linear feedback path.
We’ve choose to integrate LED’s instead of diode. It not only slighlty change
the color of the resonance but also give feeback information about the drive of the resonance path.
Since Sallen-Key can self-oscillate so it can be use as sound source. Tracking is accurate across 6 octaves.
