Hello
I assembled complete yocto2, all part is working.
but L/M/H toms&Clap section is noisy.
Yocto1 is dead silent in comparison.

Please tell me How to fix ground loop noise/hum noise.

Thanks!

voltage of the power line shows ±15v ±5v ok.

I discovered a symptom similar very much in a topic of nava.

It is the same as buzz to hear from my yocto2 clap & toms.
Do you not hear buzz from your yocto2?

uploaded buzz to hear from my clap part track.
clap volume 0%→100% repeat

this could be due to bad wiring. Try a better quality of cables

Thank you for a reply.
I confirmed that noise doesn't occur in BD/SD/RIM SHOT/COWBELL/HHT in YOCTO2 using this cable.
Also I confirmed that all section was noiseless with the same cable in yocto1.
I don't know why buzz occurs to only crap and toms.
Is there the recommended cable?
Does your yocto2 have the noise?

Did you ever fix this?

Please help me!

Maybe try out a different PSU. I had annoying hum with a cheap PSU I bought from China. These work good:

For the Toms in v1, someone found that grounding the switches case was helping, not sure if they aren't already or not.
