AI SynthesisAI004 OTA Filter (Black)

AI Synthesis AI004 OTA Filter

Slide an MS-20 inspired filter into your rack for some gnarly or subtle sculpting with the AI004 OTA VCF from AI Synthesis. Low pass mode is 12db/octave while the high pass is 6db/octave, just like the MS-20, and both can self-oscillate with the resonance set high enough. Both modes also can be overdriven when pushed and the input features a control knob that can help tame hot signals. A CV input, with attenuverter, controls the cutoff frequency and a second CV input with no attenuation is available for raw voltage. On the back is a switch that lets you turn on or off an extended resonance mode that can dial in wild peaks. For that legendary MS-20 filter sound in a compact package, grab an AI004 OTA VCF and tuck it in.
