AI Synthesis says that the AI024 Eurorack X Filter brings the clean, classic, creamy filtering of classic 80s synths to Eurorack. They tell us that it uses the same four pole analog low-pass filter topology found in classic synths like the Crumar Spirit, the Digisound-80 Modular System, Elka Synthex, Fairlight CMI II/IIx, LinnDrum, Oberheim,PPG Wave, Sequential Circuits synths, and many more. It can be purchased as a module or DIY Kit and PCB/Panel Set.
