180 Chapter 9 Working With Tracks
Once assigned to a particular type of mixer channel, the functionality of the track is
limited as follows:
As you can see, each track type handles different sorts of data and has a special
purpose. This is due to the routing of each track to a specific channel type in the Mixer.
The parameters of a track are displayed in the Inspector’s Track Parameter box.
Important: The parameters belong to the channel strip (or object) the track is routed
to, not to the track per se, so if you alter the parameters here, it will affect all tracks
assigned to this channel strip.
Most of the functions described in this chapter are identical for external MIDI, software
instrument, and audio tracks.
In addition to these track types, there are also tracks with very specific functions, such
as global tracks. Global tracks—found at the top of linear editing windows—are used
to view and edit global events, such as tempo, which affect all tracks in the
arrangement. These track types are not covered in this chapter.
