Working in the Timeline
You build your songs by arranging Real and Software
Instrument regions in the timeline.
Once you’ve added several loops to the timeline, you can make changes to their
regions in the timeline to start building the arrangement of the song.
There are several ways you can arrange regions in the timeline. You can:
• Cut, copy, and paste them
• Loop them
• Lengthen or shorten them
• Move them to another part of the timeline or to another track
• Transpose them to a different key
• Fix their timing
• Split or join them
• Rename them
About Regions
Each time you record a Real or Software Instrument, you create a region in the
instrument’s track containing the music you record. When you drag a loop to the
timeline, you create a region from the loop. Any changes you make to the region, such
as splitting or transposing it, do not change the original recording or loop.
Real Instrument regions you record are purple, Real Instrument regions created from
loops are blue, and Real Instrument regions from imported audio files are orange.
Software Instrument regions, both from recordings and from loops, are green.
Regions are the building blocks of a song. You define the feeling, build the structure,
and create change and interest in a song by arranging regions in the timeline.
