Low-pass resonant VCF

‘Ivo’ is a resonant low-pass VCF (voltage controlled filter), switchable between 2-pole (12dB/octave) and 3-pole (18dB/octave) responses, with voltage control over the feedback (resonance) and cut-off frequency . Automatically swings in 2-pole mode.

The module has two audio inputs, one with an attenuator, so it will also mix two signals at the filter input.

The module is 100% analog, using discrete transistor OTA.
