I am trying to record into Reaper using my Digitech RP 500 as the USB interface. I have done this many times in the past but now for some reason I can't get Reaper to recognize the RP 500's presence. I have both the RP 500's Inputs and Outputs enabled under "Midi Devices". I have ASIO and the RP 500's driver selected under "Devices" as I have done in the past. I can bring a new track into Reaper and arm that track for recording but it shows no detection of the RP500 and when I go to record nothing happens. There is no audio level shown on the track when it is armed either. It's not recognizing any sound coming to it. Can someone help?
