I have a new Sonuus G2M and a new Scarlet 6i6 interface I want to use with Garageband on my 2011 MacBook Pro (my Fender Mustang 1 practice amp may somehow figure into this as well, perhaps as a monitor). With these devices I'm supposed to be able to use an electric guitar or a vocal mic to generate monophonic digital MIDI input for Garageband. Alas, I haven't yet been able to figure out how to hook everything up together to make this happen. Can somebody give this poor gadget-challenged noob a little guidance as to where I'm going wrong?
