i still have a problem with snaredrum. noise section is working (around 10v of noise), but tone and snappy pots not. i don't have an idea what can be wrong

Check and resolder all op amps? Had a problem similar to yours but with my snare only noise was working on it. Seemed one of the op amps had a bad solder joint.

How does your noise work?
It should be a realy strong signal.
First my noise signal for snare and clap was realy low. I chanched the ic's in the noise part and it was here a strong noise.
And now snare and clap are ok.

I don't have oscilloscope now but checked signal on pin 9 IC33 and my multimeter shows 10V there. Also i can hear noise on headphones.

Ok,...
I think you have the same bug like mine
Now,... i have changed:
BA6110 (i think yours will be grilled too)
Q38 (you can also test this transistor on the place from cymbal - maybe it doesn´t works)
and i changed IC31, IC32, IC33
You have the same problems i had before. I fixed it with this five parts.
But - take care, be sure your M5218 are all placed right. I think this was my bad with two of it.

Thanks! I will check this parts. All M5218 are soldered right - I checked it twice.

I changeed IC31, IC32, IC33 and BA6110. Now everything works good! Thanks for help!
