no no, the synth itself powers down instead of just going dead quite when powered off, and at the end of the clip you can see the indicator light is off and the sound is powering down...
Thanks, figured somthing along the same lines...there's like 6 different little vero boards inside, crazy build...when playing it compared to all the others it's the only one where I wonder how it's composed inside..the 4 bottom knobs are like rate controls only react with each other to create rawring patterns with two tone controls that end up when fully tweeked making random chipping sounds...I've noticed the oscillator itself with all controls down is the fattest thing I've ever heard by the way it effects pedals
And since this thread is "why does my synth..." I once had the same synth hooked up but turn off, amp on and all...I was changing my bed sheets 2 feet away, and when I pulled my sheets off, the oscillator sounded, went up high then died down due to the static off my sheets.....that was a revelation.

Yup.
I'd guess that each little vero board has a decoupling cap on the power rail, and they discharge at different rates due to the various circuit loads and settings which results in the wandering when power is removed.
If ever you want to avoid that feature a kill switch on the audio output will offer abrupt mute functionality.
(I know, I know, I just repeated what vidret said - need to get caffeine BEFORE surfing)
That big 2200uf cap near the bottom left. Your build probably has something similar.
That cacophonator looks cool! Is there anyway that the circuit could be used to process incoming guitar signal, or would it only work as a standalone synthesiser? I realise the current circuit is a noisemaker on it's own, just wondered if and where another signal could enter and be modified by it... or not.
