Thank you very much tnicoson and Scott. The information is very helpful. Tnicoson, For the last few weeks, I've had the audio JACK output connected to computer speakers on my iPad Mini. I chose to do that as oppose to routing the sounds back to my keyboard...It just sounds better. I've ordered the iRIG 2. I play guitar/bass/keyboards. I know that iRIG 2 is meant for guitar, but I don't see why it would not work with my keyboard. I STILL HAVE AN OPEN QUESTION: When I'm in Garageband and I have my guitar/keyboard going through the audio interface (iRig 2), I know I can select an Amplifier for the Guitar. Should I do the same for Keyboard ?
