When you install Logic, a Logic application package is placed in your Startup Disk > Applications folder. It should be noted that this application package is more than just the Logic application itself. There is a whole bunch of stuff in the package, and all of it conspires to make Logic function. You can actually tunnel into the Logic application package by Ctrl-clicking (or right-clicking, if you have a multi-buttoned mouse) it and choosing Show Package Contents.
However, be warned: Don't move or change anything in the application package unless you know exactly what you are doing or are prepared to fully reinstall the program! Logic needs everything in the application package to remain exactly as it is or the program will not function correctly. With that in mind, let's launch Logic.
In a Finder window, navigate to the Startup Disk > Applications > Logic Pro or Logic Express, depending on which version of the program you are running.
When this book asks you to navigate to the Startup Disk or User folder, please use your own startup disk and user folder. Let's make the Logic application easy to find by putting it in your computer's Dock.
Drag the Logic application icon to the Dock and drop it there.
Close the Finder window.
In the Dock, click the Logic icon.
Logic opens, and the default workspace appears on your computer's monitor.
The workspace is the name for all of Logic's editing windows combined. It's the space you work in as you make music. Logic's default workspace represents a generic studio with 8 audio tracks, 8 Audio Instrument tracks, and 16 MIDI tracks representing all the MIDI channels found on a General MIDI (GM) synthesizer. This is an adequate base for working in Logic, but it can be improved. For example, your studio probably has more than one synthesizer. You may also have a few digital-effects units and perhaps even a sampler or two. Logic's default workspace is not set up to communicate with these extra MIDI devices, so you need to change the workspace to better represent your studio. In the "Customizing Your Setup" section of the book you will do just thattake this generic workspace and customize it to reflect the exact setup of your studio, and then save that customized setup as an Autoload Song that opens every time you launch Logic.
General MIDI (GM) is a protocol developed by Roland (a manufacturer of electronic instruments and audio effects) that defines the type, name, and order of synthesizer sound programs.
