Thanks for your reply.
On my older system with Creative ASIO Drivers I could have Windows Media Player playing a cd and at the same time I could have standalone Guitar Rig open and play along with the cd.
In the new system with Fireface UC, I can play a cd with Windows Media Player, but as soon as I open Guitar Rig the audio from Windows Media Player stops.
Also, I'm not sure how to "disable selected devices (Analog 3/4 ...) in the ASIO panel of Battery or Guitar Rig. You can only choose from a list for the Output in the ASIO panel. No matter what output I choose (Analog 1, Analog 2, etc) Windows media player audio stops when I open Guitar Rig or Battery or FM8, etc.
Another example from my old system, I could open Guitar Rig and start the loop player, I could then open Absynth or FM8 and play along with the loop from Guitar Rig.
Can't do that now.
Thanks for any further suggestions.
