thks, I will try to find a way to use a different circuit see if it changes something. BTW, I'm Canadian, I bought the Casio CDP230R in Costco.

Hi, I'm kina surprised the CDP230R isn't on the list of topics. I was wondering if any has the same problem as I do, I have an horrible noise on my audio interface(focusrite scarlett 2i4) and it comes from the keyboard's USB port. I have multiple devices connected to my USB ports and some have noise but nothing compare to the CASIO. any suggestion to fix it? thks
