Based on different behaviors, Logic uses actually 3 variations of the song, even if they all look the same in the Finder
A Song behaves like a:
Regular Song –Template Song – Project Song
Regular Song vs Project Song
Regular Songs and Project Songs have a different instruction set for handling Media Files and Auto Backups
Because these instruction sets are stored inside the song file, you cannot be 100% sure if a song file behaves like a Regular Song or a Project Song
by just looking at it in the Finder.
When you work on a song, you manage a lot of data: Record MIDI data, create Mixer movements, import audio and video files, load audio
instruments, plug-ins and sampler instruments, setup the environment and more. All this information has to be stored in your song, so the next
time you open the song, all the information is exactly there where you left it.
You can divide all the stored information into two categories: Data which is stored directly in the song and data which is only referenced to the song
• Category 1: Data which is stored in the song
o MIDI data and music related data
o Mixer data
o Environment
o Screensets, Transform Sets, Hyper Sets, Score Settings
o Song Settings (“
File > Song Settings”
)
• Category 2: Data which is not stored in the song – only a reference
o Audio Files, Apples Loops
o Sampler Instruments (EXS24)
o Samples (EXS24 Samples)
o Ultrabeat Samples
o Impulse Responses
o Movie Files
These are all media files and they can be quite big. The song file would become way too big if Logic would store all that information
inside the song file. Instead, only a reference in form of a path name to the media file is stored.
But there a two potential problem:
• When you move only your song to a different computer, all the Category 1 data will be right there, your MIDI data, Mixer setting, etc. But
wheat happened to your Category 2 data, all the media files. Your song is pointing to audio files, movie files, Sampler instruments that
might not be available on the new computer you are open up the song. The stored path names to the media files are broken!
• What if you move or delete some media files on your computer, by accident or on purpose? You also get a broke link the next time you open
a song which has a reference to those media files
Here is where the Project song comes in:
The Project Song has the instruction to copy the media files to the same parent directory. This is the same folder where the Project Song is located.
(This folder is considered the “Project Folder”). The path name reference to the media file therefore points to its Project Folder. Now all the media
files needed for that song are conveniently located in one place. If you want to move the project to a different computer/location, you just move the
folder and you know that you have all the related files. If you want to touch any media files inside a Project Folder, then you know that you might
break a reference link from the Project Song inside that folder.
