22 Chapter 1 An Introduction to Logic Pro
Mixing also entails the use of audio effects, which change, enhance, or suppress
particular song components, adding up to a unified and polished final product.
Logic Pro features numerous effects that can be used to turn your basic song into a
professionally finished project.
Logic Pro enables you to record, or automate, changes you make to track, instrument,
and effect parameters, such as volume, pan, filters, and other controls. This can be done
in real time or offline with the mouse or an external MIDI device. These changes play
back when you play the project, and can be edited independently of the musical
material. This is very useful for a number of reasons:
 You can only adjust one level or setting of a playback track, if using the computer
mouse. The ability to record and play back multiple adjustments of all track elements
allows for a sophisticated mix.
 Performances are rarely consistent. To clarify, a vocalist will often sing louder or softer
during different sections of their performance, so you may need to even out these
level changes over the course of the song, or to balance the soft and loud vocal
sections against the musical backing.
 Song dynamics (the loud and soft sections of a song) benefit from animation. In
other words, building the intensity of a song section can often be achieved by
gradual or immediate level changes. Songs that are of a consistent level throughout
tend to sound flat and lifeless.
Step 5: Exporting and bouncing
The final step of the Logic Pro music creation process is exporting your final product.
Logic Pro allows you to produce a stereo file of your completed mix in a variety of
audio file formats. You can also produce several stem files, formatted for most common
Surround encoding schemes. This is achieved in the Bounce window; simply choose
the desired outcome(s) in the available menus and press the onscreen Bounce button.
You can even burn a stereo mix directly to CD or DVD with one simple step.
