so like somebody else, i'm getting both a wet and a dry signal into my mains when i'm playing. i bought this interface for its low latency so i could take it out and play live with it, but if i were to you a pitch shift for example, i get the pitch shifted tone mixed with the dry signal which sounds awful. how can i mute the incoming dry signal? i can't find the control anywhere. i'm using the latest reaper and an asus ux501vw. sounds great otherwise.
