Analog Siren for Psychedelic Soundscapes

Is it just my little bubble or is the LM358 kind of ‘meme opamp’? I love it but it is strange i suppose. #lm358 #opamp #electronics #diyelectronics

I found the culprit... It's the #TL072 that goes into phase reversal because the gate and trigger signals are -12V when low.
After swapping it with a #LM358, the output signals for trigger and gate, including the LEDs work as intended.
This took a lot of time to find out, but I've gained some knowledge now.
