I am having a problem using the Digitech RP500 as a recording interface. I am not super knowledgeable about software recording so I am wondering if someone here may be able to help. I am using a cheaper Acer laptop computer to run Reaper. I have "enabled" both the input and output of the RP500 in the Reaper "Midi Devices" menu under "Preferences". The problem is every time I plug the RP500 into the USB port of the laptop Reaper stops functioning. I can not get projects to play or do anything while the RP500 is connected. When the RP500 is connected and I click Play the cursor will not move or do anything. As soon as I unplug the RP500 everything works great with Reaper. Could this be a problem with the sound card of the laptop? I used Reaper with my old Toshiba laptop with no problems whatsoever. Thanks in advance to anyone who can help.
