560 Chapter 25 Mixing
Surround
Logic Pro allows mixdowns in several surround formats, even if your audio hardware
only offers two outputs. Obviously, it would be difficult to mix or record in surround
with this limitation, so you’re probably best served not selecting this option if you’re
using stereo hardware.
All track, instrument, and aux channels can be individually set to different surround
formats.
To set a channel output to surround:
m Click-hold the Output slot of the desired channel strip, and choose Surround in the
menu.
The Pan control is replaced by a Surround Panner. The loudspeakers are represented by
colored dots, and the pan position is indicated by a white dot that can be grabbed and
moved.
Full details on use of the Surround facilities can be found in Chapter 35, “Working With
Surround,” on page 807.
Adjusting Elements of Multiple Channel Strips
You can select multiple channel strips in the Mixer. Once selected, all channels behave
as a temporary group, allowing you to quickly adjust a number of settings on all
selected faders by performing an operation on one of the grouped faders. Logic Pro
also offers the group functionality for channel strips (see “Working With Groups” on
page 562), but this method is often much quicker than setting up groups for many
operations.
To select multiple channel strips, do one of the following:
m Shift-click the desired channel strips.
m Click a channel background and drag over the desired channel strips (drag horizontally
across multiple channel strips over the word Inserts, or I/O text, for example).
These selection methods work on all channel types (instrument, audio, aux, and so on).
To deselect multiple channels, do one of the following:
m Click on any unselected channel or on the Mixer window background.
m Select a previously unselected track in the Arrange window.
As with individual controls on a single channel, Option-clicking a fader or knob resets
the control to a neutral value. As examples: Option-clicking a Level fader sets it (and all
grouped faders) to 0 dB, Option-clicking Send knob 3 sets it (and the third Send knob
of all grouped channels) to 0 dB (90).
