It is not essential to know about—or even open—the Environment window in order to make music with the instruments of Logic Express or your external MIDI sound generators and keyboards. When you create new instrument or external MIDI tracks (as discussed in Working with Instruments), Logic Express automatically generates Mixer channel strips, and also creates and configures any Environment objects that are needed for basic input and output.
Note: This is also true of audio channel strips (and other channel strip types, such as aux and output channel strips), but you will rarely need to access these objects in the Environment, as you have full control over the channel strips in the Mixer and Arrange window.
This chapter outlines all general concepts and techniques needed to use the Environment. Ultimately, it’s up to you to decide how to, or indeed if, you use any of the Environment’s facilities
For detailed descriptions of the Environment objects, see Environment Objects Reference.
