66 Chapter 7 Mixer, Instruments, and Effects
Note: The updating of Track Mixer channels is entirely automatic, so as you add or
delete tracks from the Arrange window’s Track List, the Track Mixer will show or hide
the corresponding MIDI or audio channel faders.
To the left of the Track Mixer window, you will see a collection of buttons, as shown.
These buttons will toggle (hide/show) the display of particular classes of channel strips.
The button on the top—Global—toggles the display between channels which
correspond to those that exist in the Arrange window’s Track List, and all defined MIDI
Instrument and Audio Objects that exist in the song’s Environment (more on this in a
moment).
The other buttons can be clicked individually, in order to display all channels of the
selected class. Multiple classes can be selected for display in the Track Mixer by holding
Shift while clicking on the individual buttons.
Please try the various Track Mixer display modes with the Tutorial song to get a feel for
how this view functionality works.
Mixer and Audio Objects in the Environment
Another mixer view is offered by Logic’s Environment. You can access the Environment
via the Windows > Environment menu option, or Command-7
. If you don’t see any mixer
channels in the new window, please select the Audio option shown in the Layer pull-
down menu to the left of the Environment window.
The Environment Mixer looks very similar to the Track Mixer. However, there are two
important differences:
• This Mixer does not change its look dynamically to reflect the Arrange window’s track
order. Rather, it shows all Audio Objects in user-defined order.
• In the Environment Mixer, additional channels can be inserted by creating and
configuring new Audio Objects.
Various Audio Objects
A number of tracks, instruments, busses, and so on were created when you ran the
Logic Setup Assistant. These different types of Audio Objects are based around the same
fundamental Environment Object—namely the Audio Object—but each was
configured differently, and has distinct facilities.
