1. Garageband Usb Input

I've just plugged my mac back into my interface and Guitar Rig Kontrol after recording elsewhere, but when I go to click record in the Rig plug in track, a message comes up with 'No input source selected'.

With the input selected, this means that your computer will listen for sound coming through the device and allow you to either monitor or record that stream. Once this is done, whatever audio or DAW software you use (in this case GarageBand) should recognize that the Mac OS is already listening for your device. Open GarageBand’s preferences, select the Audio/MIDI tab and from the Audio Output and Audio Input pop-up menus choose Soundflower (2ch). Close the Preferences window. From the Input source.

I've gone back and checked all the audio and project settings and it all looks exactly the same as before, and the guitar's plugged in fine. And the input bar in audio settings, set as Rig Kontrol/Fast Track out displays the signal - it seems to be 'selected'. Is there anything else I'm missing??
