Apple Logic Pro 9 - Manual (Page 1178)

• LR, C, and Ls-Rs shown on three separate tabs denotes left/right stereo, center mono,
left/right surround in stereo.
Each effect tab is, in essence, a discrete effect unit for each channel (or channel pair). As
such, you can have different plug-in parameters for the LR tab, the C tab, the Ls-Rs tab,
and the LFE tab. When you save plug-in settings, the parameter values of each tab are
saved.
You can assign these different mono or stereo configurations in the Configuration tab.
Configuring Multi-Channel Effects
The Configuration tab allows you to determine how parameter changes affect the plug-in
instances.

• Link menu: Determines which effects are linked. If you link effects, parameter changes
apply to all effects in the linked group. You can choose between three groups: A, B,
and C. Channels set to none (“-”) operate independently. Each group features its own
tab.
• Bypass button: Click to bypass the channel: It is routed around the effect. This is useful
when individual channels should be exempt from processing by a particular plug-in.
Note: If the Bypass button of a grouped channel is clicked, all channels in the group are
routed around the effect.
