JU60-VCF is an analog 4-pole low pass filter adaptation of Roland Juno-6/60 using a vintage IR3109 chip with a BA662 OTA chip in the resonance feedback loop. This topology was also used on the Jupiter-8, with a switch for tapping the 2-pole mode. Resonance will self-oscillate and produces a nice sine wave alone. JU60-VCF won’t turn your system into a polyphonic synth, but it has a classic sound at a sweet price.
