Ivo Analog Low Pass Filter

Expert Sleepers Ivo

Joining the ranks of killer Eurorack filters, the fully analog Ivo from Expert Sleepers is a resonant low pass filter with switchable filter responses. Offering both 2-pole12dB/Oct and 3-pole 18dB/Oct repsonses, Ivo has plenty of character on tap to spruce up your patches. With voltage control over Cutoff with attenuation, another dedicated Cutoff CV input set to ~1v/Oct, and a dedicated Feedback (resonance) control, the Ivo has everything you would expect from a filter in a compact, sleek panel. In the 2-pole setting, the module will self-oscillate, there's two input mixing—one audio input with an attenuator—discrete transistor OTAs, and Expert Sleepers's signature LED-ring jacks. Dial in your ideal sounds with the Ivo from Expert Sleepers.
