Lesson 12. Setting Up the Audio Environment > Exploring Audio Object Parameters

Exploring Audio Object Parameters

Audio Objects are the chameleons of Logic. An Audio Object can assume the form of any audio channel available to your system—a track channel, an Audio Instrument channel, a bus, or an output. It's up to you to determine what each Audio Object will be, and you do so by specifying which channel the Audio Object will play out of. This is the single most important concept about Audio Objects, so let's create an audio track, an Audio Instrument, a bus, and an Output Object to see how it works.

1.
In the Environment's Object Parameter box, click and hold the word Track1 (to the right of the Channel parameter).

A hierarchical menu opens to display a list of available channels.

Note

Items in boldface indicate that the channel is assigned to an Audio Object in the Environment. In the example, only Track 1 is assigned to an Audio Object, so only Track 1 is bold.

2.
Leave the Channel parameter set to Track 1.

The Audio Object has been named (Audio Object). That doesn't tell you very much about its function, and in fact, it's best to give all Objects descriptive names that indicate the type of channel the Audio Object represents, such as electric guitar or lead vocal.

Tip

Names in parentheses are provided by Logic. If you see such a name, it's a good idea to change it to something more descriptive of the Object's purpose.

3.
At the top of the Object Parameter box, click the words (Audio Object), and name the Audio Object Track 1.

4.
Create a new Audio Object and expand it to the channel view.

5.
This time, from the Object Parameter box's Channel menu, choose Instrument > Instrument 1.

The Audio Object becomes an Audio Instrument channel.

6.
Name the Object Inst 1.

7.
Click and hold the channel's Input slot, and assign an Audio Instrument.

The Audio Instrument opens in a plug-in window.

8.
Close the Instrument plug-in window.

9.
Create a new Audio Object and expand it to the channel view.

10.
From the Object Parameter box's Channel menu, choose Bus > Bus 1.

11.
Name the Object Bus 1.

12.
Create a new Audio Object and expand it to the channel view.

13.
From the Object Parameter box's Channel menu, choose OutputStereo > Output 1-2.

14.
Name the Object Output 1-2.

Voilà! You now have four Audio Objects, and each is assigned to a different audio channel. As you can see, it's very easy to create exactly the type and number of Audio Objects you need for your unique way of making music.
