How Effects Are Grouped
Logic hierarchically groups effects as follows:
• Audio Channel Type—either Stereo, Mono/Stereo or Mono. To explain:
• Stereo: Stereo in, stereo out (True stereo). Both input signals are processed
separately, so the stereo qualities of the signal remain unchanged—this is
important for summed or stereo bus signals used as inserts.
• Mono/Stereo: Mono in/Stereo out. For use with mono signals only, but the effect
output is stereo. Commonly used on the following mono signals: Chorus for bass,
Reverb for lead vocal.
• Mono: Mono in, mono out. Should only be used on mono signals. Typical
applications are for EQ’s or dynamics processing (Kick, Snare, Bass).
• By origin (Logic or third-party): Logic, Audio Units. Grouping of effects in this fashion
makes the selection of effects simpler.
• By effect definition—Dynamic, Modulation, Reverb, Filter, and so on. The effect
definition groups effects of a particular type together.
Logic automatically limits the available effect types shown in the plug-in menus to
match the Audio Object’s signal I/O settings. In other words, if an Audio Object is
mono, then only mono (and mono/stereo) effects will be available in the Plug-in menu.
This also applies to stereo Audio Objects with only stereo plug-ins being available. It is
possible to override these settings by pressing and holding Option before selecting the
Plug-in menu on an Audio Object.
If you choose to use a plug-in that does not match the Audio Objects’ signal I/O
flow, Logic will be forced to do a data stream conversion, which places a greater
strain on the CPU, resulting in fewer effects and/or tracks.
Channel Strip Setting
Logic’s Mixer windows allow you to save and load multiple plug-ins (inclusive of their
settings files) via the arrow pull-down menu alongside the word Inserts on channel
strips. The entire channel strip can be stored and recalled for use on any suitable Audio
Object, allowing common chains of effects such as Reverb, Chorus, and Delay to be
loaded far more quickly than individually inserting each plug-in.
To load a Channel Strip setting:
m Click on the word Insert on any channel strip. The Channel Strip Settings menu opens,
offering you a list of all available Channel Strip settingsand menu functions.
The Channel Strip Settings menu also offers you all GarageBand channel strips.
