Twee tips gevonden op Apple Discussions:[list=1:d974b4fa81][*:d974b4fa81]You want to be able to synchronize your slideshow presentation with an audio track.
To do this you first create your slideshow, with all of the Builds and Transitions in place. Then you open the Inspector / Documents / Audio window. Here you have the ability to bring in an audio track to use as a Soundtrack (either by importing it from iTunes or dragging the audio file into the Soundtrack window) and then Recording it as the Soundtrack for the slideshow presentation.
When you click the Record button, the audio track will begin playing and the slideshow will begin. Then just Click in sync with the music to trigger the Builds and Transitions you have created. Once completed, the slideshow presentation will play with the music and slides synchronized as you recorded them.
If you make a mistake while recording, you will need to start over.
To learn how to do this effectively, I suggest you create a short trial presentation of five or six slides and practice with this until you get the feel of the process. Then go ahead and do your complete presentation.
