On the Audiobus control panel in your instrument app, tap the Garageband icon to bring up the controls. There you’ll see rewind, play, and record buttons.  If you need to, hit rewind to make sure you’re at the beginning of your song, and then hit record to begin recording.

To play back what you recorded, you can use the controls on the right from within the instrument app. Alternatively, tap the return button underneath the Garageband icon to return to Garageband.  There you can check that you recorded made it into the edit window.

Now that you can connect and record with Garageband and Audiobus, try using the guitar amp simulator by selecting Guitar Amp instead of Audio Recorder in step 4 for some cool effects.  Or, if you have and Audiobus-enabled effect apps, go back to Audiobus and insert those into the effect slot in between your input and output apps and see what happens.

Have fun!
