Hey guys! So my band just got a new PA and we decided to get the Mackie ProFxv2 as our mixer. We have everything set up and sounding great but the problem is that we can not get the usb to actually record anything. It will play back all day long but when it comes to recording, it will not even monitor what we are trying to record. We are using a new Windows 10 laptop with Reaper. Any help would be greatly appreciated.
