I just installed the Presonus on my computer. I am running Windows 7 Home Premium. I seldom use the interface to record but just to use from the computer to a Boss 1600.
I am getting some distortion from BnB and RealBand through the Presonus. I installed the driver that came with the unit. Any thoughts? It powered up well and started playing right away...just some background distortion. The volumes are set well within range so this should not be a problem.
It's sure a well built little unit.
