Thanks for answer Misa ! I always used the same tool to check values !! hahaha

Re-checked, all values are right, actually, I've finished my Yocto and all voices works fine except for CLAP, MARACAS, and OPEN HAT that don't produce any sound. SNAPPY pot in Snare drum also does nothing. It seems to be something related to Noise generator part, but if it's the problem, why is ClosedHat is working then?

mrgif have you read the other thread over here:

viewtopic.php?f=16&t=155

it has a lot of useful info. Apparently even if the values of the resistors are all up to spec it can stil lhappen that because of the 5% tolerance, you can get quite a different resistance value. so it might be worth trying out another value for R127 if you are sure that everything else worked.

I replaced mine with a 47K and I was able to trim noise to 130mV.

Hope that helps...
