I just bought the elektron overhub V2, where I have connected usb / midi from styrmon nightsky, styrmon volante, Moog mathiarch, TD-3 MO, keystep pro, Focusrite Clarett + 4Pre to overhub. and from the electron hub v2 to the motherboard to a usb 3 input, all instruments have their own power supply. Nektar Impact LX Mini is on its own USB 2 on the motherboard as it has USB power.
I get USB noise loop from instrument and pedals in my earphones, when everything is connected, but disappears when I disconnect TD-3 MO, styrmon volante and nightsky from overhub. when all the noise was gone I removed the Clarett + and put it to its own usb on the motherboard as well.
I have tested different USB ports on the motherboard but get the same problem.
how do i solve the problem? I am running a hybrid installation with usb / midi hardware connected to cubase 12? bought overhub to have all usb midi gathered for better cabling and reduce the number of connected usb devices in the motherboard, and that overhub optimizes the data flow for midi / usb what I understood.
where does the sound and the noise come from? and will it be better if I buy a pcie usb3 card inserted direct to motherboard and connect the electron hub to the pcie card?
or are there other ways? like connecting all instruments and pedals in a special order in overhub?
need all the advice I can get, then I should not be the first with this problem. I need to buy another usbhub to connect more usb. but need to fix this problem first and understand what the problem is coming from.
are there no usb pci / pcie cards that have optimized chips for audio? where can you connect usb sound card and overhub?
or how should I think? and what do I need to do to get a quiet system.
there are motherboards that are optimized for this, such as asus proart z690 or asus proart B660. or something else?
