Magpie Modular repanel for Non Linear Circuits - VC ADSR
Basically grabbed the classic Jacky/Kirschman 555 ADSR circuit from 1980 and replaced the pots for Attack, Decay and Release with LDRs inside black boxes (BBX).
Not sure why it hasn’t been done before, it is a simple circuit and the results are fun; lots of wobbly, evolving envelopes.
