Hi.

I have troubles with my Multiface, Mainbaord, Speakers and evrything get connected with the Ground from my Mainboard.

When i start the Computer, there is not a big problem, but if i start Cubase, than i can here the Computer work very loud from the speaker.

When my Synths only connected to the Multiface II (via Audio) there is no "noise", but if I put the Ground from the Mainboard to a Synth, a noise (like from the Speakers [here the Computer]) comes from the Synth to the Multiface II input.

For example: Minibrute only Audio and MIDI connected to the Multiface II = no problem > but when i plug the USB-Cabel from MINIBRUTE to the Mainboard, there comes a "computer noise" to the imput.

I tryed to use the Computer Powersupply instead of the PCIe Power, but this has NO effect.

I also forced my friends and some Froums to help me, but we can find no solution exept to put a 1:1 Transformer between Speakers and Multiface...

Has anyone an Idea, how i can get rid of this hell?

Thanks in Advance!
