Use surround effects in Logic Pro
Logic Pro offers a number of surround effect plug-ins, and also includes surround versions
of instrument plug-ins such as the Sculpture and ES2 synthesizers, and the Sampler
instrument. Your AudioUnits instruments and effects may also work in surround.
Important: The project surround format determines the surround format of plug-ins. For
more information, see Set the surround format for a Logic Pro project.
Insert a surround effect plug-in
1. In Logic Pro, set the channel strip output to Surround. See Set the channel strip output
format in Logic Pro.
2. Click any Insert slot, then navigate to the Mono → Surround (on mono channels), Stereo
→ Surround (on stereo channels), or Surround version (on surround channels) of the
plug-in you want to use.
For example, on a stereo format channel strip, navigate to Delay > Delay Designer >
Stereo → 5.1 (ITU 775). If the project surround format is set to 7.1 (SDDS), the Plug-in
pop-up menu of a stereo channel strip is displayed as follows:Delay > Delay Designer >
Stereo → 7.1 (SDDS).
Tip: Its possible to release the pointer on the plug-in name, instead of navigating all the
way through the hierarchy to the channel format. The plug-in opens automatically using the
default channel strip format.
Insert plug-ins that do not match the channel format
In Logic Pro, option-click a channel strip Insert slot.
The Plug-in pop-up menu displays all available formats for the plug-in, rather than
being limited to the matching format. Any down- or upmixing that may be necessary will
happen automatically.
The default format of software instruments is stereo (if available). Mono and the
project surround format are offered as additional formats.
The default format of effects plug-ins is the current channel strip format (at the
insert point in the signal path).
All plug-in format variations (based on the current channel strip input format, and
all available plug-in output formats) are offered, up to the maximum allowed by the
project surround format.
Note: This applies only if the output of the channel strip is already routed to a
surround bus or output.
LogicPro effects plug-ins can also be operated in a multi-mono configuration, based
on the project surround format.
