Bought an iPad2, iRig and the Belkin Bluetooth Audio Receiver. I was hoping to use Garage Band or AmpliTube to plug my guitar through my iPad2 then out through our band's PA sound system for live performances. That would enable me to play guitar for live performances without carrying an amplifier. To my disappointment, I learned that Garage Band does not permit any audio IN functions (such as through iRig) while Bluetooth Audio OUT is enabled (AirPlay-Bluetooth-HDMI). Garage Band provides a message box which specifically says that and requires you choose one or the other. AmpliTube does not even give you a message. It just won't provide any audio output through Bluetooth. Any suggestions? Other apps? Other hardware other than iRig? BTW the Belkin Bluetooth Audi Receiver is otherwise an awesome product.
