POLEY

2140 based pole-mixing VCF by maffez

This is a pole mixing filter based on the SSI2140 filter IC (remake of SSM2040). What’s different here is that you have pole mixing for different filter responses (bandpass, highpass, etc.), and compensation for level loss on higher resonance settings. The PCB is fitted for an expansion panel not yet designed) that gives you reso CV and more filter types.
