Hello! I don't know where the problem is: AmpliTube or the iRig HD 2.
I recently purchased the iRig HD 2 and downloaded AmpliTube onto my iPad Pro. I followed the instructions using the provided lightning cable to hook up my iRig HD 2 to my iPad. The Blue light turns on, but that's about it. The App isn't detecting any sound nor does the iRig HD 2 change any color when I play to indicate that it's picking up any sound.
Has this happened to anyone before? Does anyone know the answer to fixing this problem?
