    Passive LPG is live!!

    Here, the VCO is sending a pure square wave melodies into the low pass gate. The Maths is in repeat mode, sending very short envelopes to the LPG.

    In the middle, the switch lets all the sound through and accents the sound with the control voltage coming in.

    But switched to the top (bouncy!) and bottom (mellow!), the filter slope is modified by bigger capacitors so that only the CV pings can be heard.

      Final version of the DIY passive Low Pass Gate. From design to build in about 3-4 days.

      Had some troubleshooting to do with ground connections but got it working without too much fuss.

      I built this specifically to go in the case in the video because I needed a simple filter for a different dimension on the existing sound palette.
