Hi JRod :)
Audio Files can be big creatures! Remember if you are saving the Sampler Instrument files and the samples too these can be very big as well!
It's important to remember in Logic a region is NOT an audio file and vice versa. I say this because you can use one audio file hundreds of times in your project and the size of your project will not be much bigger than the audio file and the project file.
The number of track, regions etc in your project don't make for a large project.
The number of audio files you have imported into your project (whether in use or not) do.
The .logic file is essentially a reference file that tells logic where to find this and that audio file, SI, MIDI region etc...
The backups will also not be very big.
One tip, in the Finder to see the size of a file or folder either:
- Use Column view mode and single click an item and you will see it's size
- Select an item and choose File > Get Info (Command-I)
In your previous thread I suggested selecting unused audio files and deleting them in the Audio Bin.
Another option is to consider the sample rate you are recording at. Audio recorded at 88.2 Khz will be about twice the size of 44.1 khz audio files.
Do check that you haven't saved complete sample sets to your project folder too. This will be useful if you have created your own EXS24 Sample Instruments that another user doesn't have and you want to transfer your project to him/her... if not it can take a massive amount of room.
What about 'takes'. Imagine you have 10 Audio tracks and each track has 10 takes...!
Consider bouncing tracks to a single audio file when you are happy with them.
Import those files into a new project.
