Looks like you need to build a bank / chase - which is simply a set of scenes.
Music chase playback is triggering one or more chases to play back with the length of the scenes set by the timing of the music and the scene to scene fade time set by <Fade Time>. The general instructions for music scene playback are as follows:
To playback all the scenes in bank 3, with timing set by the music:
1. Press <Music/Bank Copy> to put the board in music playback mode. The Music Trigger indicator comes on.
2. Use the chase buttons to select the chase that will be played back.
3. Use <Fade Time> to set the fade time between scenes.
EDIT - Correction:
Music Scene playback is the triggering an entire bank of 8 scenes to play in order in a loop, in other words, scenes 1, 2, 3, 4, 5, 6, 7, 8, 1, 2, and so on, with the length of the scenes set by the timing of the music and the scene-to-scene fade time set by <Fade Time>. The general instructions for Music Scene playback are as follows:
To playback all the scenes in bank 3, with timing set by the music:

2. Use the bank buttons to select the bank of scene that will be played back.
