I am using GPO and NI's guitar rig. Does anyone know how I can use both these applications at the same time? I am using Digidesigns ASIO driver. When I start either GPO or Guitar Rig one or the other can't find the driver. I know I can use Pro Tools to hear both apps at the same time as plug-ins, but because of NI's windows bug it's a real pain in the butt. I would really like to be able to use them as stand alone units for the writing process, and then go into Pro Tools for final mixing and mastering.
