Is there a way to plug the usb of the Helix LT to the PC so I can use only the HX edit and not as an audio interface? I already run my monitors through a Scarlett interface and want to keep it that way. When I try to use the usb I get a huge amount of echo on everything including youtube videos etc. If I use the Helix into the Scarlett it works great but I have to unplug the usb and loose the HX edit functionallity.
