So I recently bought a FX100. When connecting with my phone (iPhone 6), it says that it has connected. But then when I try to alter any settings it just doesn't work. There is no response, while it says that it's connected. I tried updating, but the updating via mac doesn't work. The device shows up but doesn't install. Does anyone know what to do?

Is it possible to use a bass guitar on the AMPLIFi 150, or even on the 75?
