Hello all,
I found a schematic for an ADSR envelope circuit (the third one at https://www.schmitzbits.de/adsr.html), and I tested it in LT SPICE to ensure it works with modified values as I do not have 2M potentiometers. However when I realized the circuit on a breadboard it did not respond when I drove the GATE input with my function generator. I noticed a transient response on my oscilloscope when I tried replacing the 0.01uF film capacitor with different values. However I only captured a short RC charging transient when I set it to single shot mode to see what was happening. Unless I made an oversight with the wiring I am at a loss for what went wrong. Would anyone be able to help me?
I should also note that the pots are in the order Attack, Decay, Sustain, Release, on the bread board.
Thank you very much and please let me know if you need more information.
