I found the missing octave
I share the problem, I hope, it can help somebody.
I tried the audio probe, and when I toched the Doct1 pot's middle pin with the multimeter, I could hear some noise. This noise was different from the earlier, it was louder. So I found out, my potmeter was dead. I don' know how and why, but after desolder it, I couldn't measure any resistance between any pins of the potmeter. I will buy an other, and try it.
Thanks for the idea.
