I set the Line 6 KB37 ASIO driver to do Mic/Instrument via
Send 1-2 Instrument
Send 3-4 Mic
I create a project with Cubase 7.5 and look at the drivers mappings and it always says Send 1-2 is inactive, so it auto picks the mic for guitar and vocal tracks, which I switch back to 1-2 for guitar and its dead ( obviously as its inactive )
So I can either get MIDO and guitar into Cubase ( if I change the KB37 driver sends ) at the same time or MIDI and Mic into Cubase at the same time, but never all 3
I thought I could do all 3 inputs at the same time into a DAW?
