So, here is a thread [don’t worry I won’t post as much] for units I made. The first uses a VCA to reduce the amplitude of a signal, out1, to the level of a2. a1 resets it. It works via counters [an ingenious solution], and I wanted to go for a fine grain over speed: you would need to go through at least 2500 cycles before reaching zero amplitude.
