Hi Cold,
Sorry mate, I didn't explain well enough. I have turned up the volume of the monitors loud enough so that's out of the equation as that's something i'd originally thought of.
I am going guitar in to Kemper ------> UAD 16 -----> Pro Tools. Now the sound i get from the UAD virtual console is muted however when unmuted it sounds the same as the sound i get in Pro Tools before recording.
I've seen several other people have had this problem but with nothing to solve it on their posts. This being in Pro Tools, Cubase, Logic and Cakewalk. It sounds a lot more full but when I 'playback' it sounds different. If i had to describe iti'd say empty in comparison.
