Designs from: Skull & Circuits (https://www.skullandcircuits.com/vca-1-2/ - Moritz Klein (https://www.ericasynths.lv/shop/diy-kits-1/edu-diy-vca/) Features: If we expect or plan on developing modules which use the two clockwise-most pins, looking from below. Clock rate goes down when resistance goes up, opposite to expectation.
