Hi and thanks siverhead! Let me say that your level of detail was very helpful, and made me realise that I was not as specific as I needed to be when posing my dilemma. Let me explain, I have a Helix rack, using a W10 PC with Reaper 6:
-I have connected guitar and mic to respective H>elix inputs.
-I have separate blocks, one for guitar and one for microphone, no connection. Guitar out usb1/2, mic out usb 3/4.
-Helix is connected to PC via usb
- in global settings I have increased the gain all the way, just to be sure.
-I have created two tracks in reaper and designated guitar in "guitar" from the above 1/2 out from Helix, and likewise mic in from the 3/4 Helix out
-Reaper has been used countless times and is ASIO source from Helix, has worked fine previously
What I get is a very strong signal from the guitar, but no signal from the mic. I have worked with the routing matrix in Reaper, and tried all sorts of variations, but either get only guitar signal or no signal at all as I have screwed something up. At this point I close Reaper and start over, usually getting a very strong guitar signal but no mic signal input. There are so many adjustments, what could be missed?!
