Hey, I know this is off topic, but I am working on an octave generator, if you want to check it out...
I am still working on getting rid of the beeping, but it does produce an octave down...
For all you starwars fans...

Sorry, downsized by request.

Did I mention I love bass?

Hi guys !
This old problem with POG v1, the "Always ON" syndrome or "Always bypass" problem, was reported but never solved.
I decided to experiment with sig gen and oscillo on my POG 1 and my problems came from Reset lines :

You can read my subject on that :

Maybe you can help me finding the origin of the problem,
