Voltage controlled Multimode filter based on 3350 chip.

The core circuit is based on a 3350 IC. CEM3350, AS3350 or an equivalent chip will work. In addition to frequency and resonance potentiometers, it has CV input and amount potentiometer for frequency and resonance. It comes with an integrated audio mixer with 2 audio inputs. Input 1 is set to maximum volume, while input 2 has a volume control to achieve the desired mix. The goal is to connect 2 oscillators without needing a mixer module. It has 3 outputs: low pass, high pass and bend pass.
The front panel is also made of PCB and screen printed by hand.
