GarageBand 2.0 song does not automatically follow key change

When you record a song in GarageBand 2.0.1 or later, all tracks automatically follow any subsequent changes you make to both the key and tempo. However, a song recorded in GarageBand 2.0 will only follow tempo changes—not key changes.

You can easily transpose a GarageBand 2.0 recording to a new key by following these steps:

1. Select an audio recording in the song.
2. Click the Edit button to open the Audio Editor.
3. Set the Region Pitch slider to the number of semitones needed to transpose the region to the song's new key.
   
   
   
   In the example above, we transposed our audio recording up two semitones to change the key from C to D.
4. Repeat for each audio recording in the song.
