Hello. I have been able to use a solo and a 2i2 to connect as the adaptor on RS remastered. However, I just bought the new 414 and it doen't seem to recognize the guitar signal. It shows a Realtone Cable connected, but there is no sound coming through. I've only tried input 1 to this point as the other models looked to input 1 foer the signal. Has anyone gotten the new 4th gen 4i4 to work? Thanks in advance!
