Expert Sleepers Ivo

Lowpass Filter

Ivo by Expert Sleepers is an analog lowpass filter that has a nice, punchy sound thanks to the transistor OTA circuit used. The filter is switchable between 12 dB and 18 dB, in 12 dB mode the resonance reaches self-oscillation. Two audio inputs save an additional mixer module, depending on the patch. Three control voltage inputs, two of them with attenuators bring the necessary control of the filtering.
