The GarageBand 5.1 update, released August 3, 2009, now allows users to add up to three track or Audio Units effects to an Electric Guitar track. As this was NOT the case with GarageBand 5.0, several pages in this ebook now have outdated information. The pages affected are as follows:

p. 46: In the sidebar Different Strokes, the first bullet should now read: Recording direct into an Electric Guitar track gives you access to GarageBand’s brand new guitar amp models, which by and large sound pretty great for virtual amps. You also get to use Garageband's new virtual stompboxes for effects, along with up to three of the standard track effects.

p. 88: The third box, Stompbox Effects, should now read: Stompbox effects are available only in Electric Guitar tracks. (For more details, see Stompboxes.)

The track effects slots on an Electric Guitar track can be a little hard to find at first. To use them, double-click the amp illustration to show its backside. Now click the arrow just below the floorboards to show the track effect slots.

The 5.1 update also addresses a potential security issue: when launched, GarageBand 5.0 would set Safari to always accept cookies, which may have allowed third parties to track your Web activity. The update also improves support for Apogee audio interfaces, speeds up switching to full screen in Magic GarageBand, and improves access to audio monitoring settings.
