I am not sure I understood the point of asio4all correctly. I have two USB Audio interfaces (Yamaha AG06 and Line6 Pod X3) that I am using in Cubase AI 8. I use the POD to record the guitar, and the AG06 as a mixer and for a keyboard.
If I switch on two devices in asio4all and I added the corresponding busses in Cubase , shouldn't the sound be redirected to both ?
How can I use one device for recording and the other one for playing (except switching from one driver to the other) ? If this is not possible with asio4all, what is the point of the ability to turn on more than one device at the same time ?
