Apple Logic Pro 9 - Manual (Page 770)

To change the level meter scale
1 Open Display preferences by doing one of the following:
• Choose Logic Pro > Preferences > Display (or use the Open Display Preferences key
command).
• Click the Preferences button in the Arrange toolbar, then choose Display from the
pop-up menu.
2 Click the Mixer tab, then choose a value in the Scale pop-up menu.
• Exponential: Provides higher display resolution in the upper range.
• Sectional dB-linear: Provides the best possible display resolution across the entire level
range.
Switching Between Channel Strip Volume Levels
You can use the following key commands to quickly switch between two different volume
levels on a channel strip:
• Toggle Level of Audio Channel Strips
• Toggle Level of Auxiliary Channel Strips
• Toggle Level of Output Channel Strips
• Toggle Level of Input Channel Strips
• Toggle Level of Bus Channel Strips
To switch between two volume levels
1 Select an audio channel strip, for example.
2 Set the Volume fader to the required level.
3 Use the “Toggle Level of Audio Channel Strips” key command.
Note that the channel strip’s Volume fader is all the way down.
4 Set the Volume fader to an alternative level.
The “Toggle Levels of Audio Channel Strips” key command now toggles between the
two volume levels. It does so for all channel strips of the same type at once, allowing you
to create two different mixes from one set of channel strips.
Setting Pan, Balance, or Surround Position in the Mixer
Rather than having instruments compete with one another in your mix, you can separate
elements by positioning audio and instruments in the stereo mix from left to right.
