New circuit design for a more powerfull sound and new toggle switch for lowpass/highpass. The switch turn lowpass to high pass filter with the same characteristics and the same cut frequency !
This clone of the mythical MS-20 vintage filter offers a spectacular Lowpass, with a powerful resonance! The cutoff is controllable with the potentiometer and via a CV input with a fine tune.
Hint: The filter can even resonate with itself by putting the PEAK at maximum to create a controllable oscillator at 1v / oct via the Cv input!
