This happens only with a guitar plugged in the soundcard so i guess the guitar picks up the interference from the lights or something...
When i touch the strings of the guitar, the chassis of the mixer or the chassis of my soundcard the noise lessens, for instance if i step on the softstep really hard and take a huge grip on my mixer with all my hand then it goes away completely. If i only touch the mixer with one finger then the noise just lessens.
And yes, when i turn off all the blue lighting (EL ON/OFF in the software editor), there is no more noise problem.
Now if i remove the guitar from the equation, with all my equipment of, just the softstep powered via usb from my computer, i can still hear the noise in the softstep itself it i put it close to my ear. And the noise stops when i turn off the lights.
