thanks g.gabba for pointing out to me the value of tempco resistance.
I put a 2k2 resistor in parallel with the tempco and now it seems to work!
thank you!

ahhh and yes i have the gnd of the kb and gnd of the psu connected

Excuse me for not being clear. It is my very first experience in a forum Embarassed

I just measured the tempco resistance and yes, it's 2k.
yep,the same in all the v/oct input.

Hi g.gabba and thank you for your answer.
at 0v on my keyboard,i tune the frequency pot at 55hz.then when i play 1v up(1 oct) the frequency goes at 220hz.
i checked the voltage of my keyboard and is ...
