I own Amplitube 5 and Irig 2 HD and I have always used them without issues. Lately, I've been using Amplitube 5 with another card that has two inputs, a left and a right input. What happens is that I hear a sort of slapped delay that is nothing more than my doubled input signal. This happens even when disabling the amplifier, the cabinet, and the room, or using the Direct Line and by-passing everything.
My idea was to bypass the amplifier and the cabinet section and use only the delay, chorus, and reverb added at the end of the signal chain.
Cheers and thanks
