Can you see that there is a signal on P2 and P6 at all? If not, then there will not be much of an effect when changing their setting. I would suggest you try to trace the signal Ue via P4 to OV2 and OV3, then from Ue via OV1 to P2 and OV2 and OV3 and finally from Ue via OV5 to P6 and OV2 and OV3. Doing this systematically should help you find the problem in your build.

That’s unfortunately what #1222 outputs…

Sorry, I was wrong!
Output of the oscillator, input of Analog-Multiplitierer, is AC.
So the blue marker numbered ‘2’ on the left hand side of the screen is not at 0 Volts?

Blue marker numbered ‘2’ is AC.
I am very happy that my new circuit was finished today! For me as an OPAmp newbie a hard work.
I am very excited about the now following tests and what to do with the ‘Analog-Multiplizierer’.
Many thanks to Jos for the support, which was very helpful to me.

I’d be very proud of a neat build like that.

Oh, nice. You managed to get it to work. You can use Funk-O-Matic for a lot of tasks. If you want a fun result then use it as a wavefolder. That will make a simple wave into something more complex which is likely to sound more interesting.
My pleasure!
