Yamaha 01x makes noise when connected via firewire?!

Yamaha 01x makes noise when connected via firewire?!


I just got a 01x (for really really cheap!)

Otherwise the unit seems ok, but when I connect the firewire and set the 01x as a slave I get this faint pulsating "screech" coming from the analog outputs of the 01x. This little screeching sound appears about a little less than a second interwals and it drives me nuts.
When I disconnect the firewire, the noise disappears.

Has anyone ever encountered this with 01x, could it be just my unit or does others have this, IMO this could be something of which others suffer too.

Got any ideas how to get rid of this?

Can I lift the ground on firewire ?

This sounds like noise comming in from the power or ground connections of the firewire. I haven't looked lately, but there is probably a way to disconnect the power (4 connection adapter of some sort) on the firewire.

Going through your power distribution and your grounding scheme may fix it too.
