My studio is re-wired and everything works, mostly

I’m finished with re-wiring my studio and it works great, for the most part. All my gear is now plugged into the Behringer PX3000 Ultrapatch Pro. I can very easily select which ones should connect to my sound cards, depending on what gear I want to use and record simultaneously.

Technically I could do this earlier but now it’s so much easier. The thing that works best for me when making music is that when I get an idea I want act on it immediately. Earlier it was such a hassle each time I wanted to record different hardware synths, so I tended to always stick with the same – which is a bit bad for creativity. For me anyway.

The only thing I need to solve now is to get rid of the USB noise / hiss that recently, somehow found a way into the sound from my Eurorack modules. The noise originates from the computer, via the external sound cards. I earlier had the same problems with the sound from a couple of the synths with USB (The Blofeld and the Modemachines Xoxbox) but solved it using a couple of cheap Ground loop isolators.

I tried the same approach with the sound out from the Eurorack modules. The USB noise was removed but so was also everything below 2000 Herz. I’ve ordered different isolators from Thomann. If that doesn’t work I will have to get something more expensive.
