Discrete Transistor Low Pass Gate
The SetonixSynth Boing! is a Light Dependent Resistor-controlled low pass filter. It takes its primary inspiration from ultra-simple yet delightful passive Vactrol Low Pass Gate modules such as the PassiVac and DPLPG, but adds JFET transistor input and output stages and an active LED control circuit, thus enabling the introduction of wonderful Feedback and Trigger functions, LED brightness offset, and a second filter stage. Combined, these features allow for incredible variable-cutoff overdrive and low pass filter sounds in addition to bouncy LPG Bongos and more.
