Feedback Modules - Hi-Fusion VCF

HI-FUSION is a remake of the classic Polyfusion from the 70s with some improvements.
It is a low pass OTA VCF based on the well known LM13700 ic.
We chose to make this circuit because it's v/oct stable, and the trimmers allow to calibrate it properly.
It has a switch for 2 pole and 4 pole configuration, each with it's own character and timbre.
This design produces nice sounding filter fm results.
