How Mono , Stereo, and Surround Effects Are Handled
You can insert mono, stereo, or surround instances of effects into channel strips.
Only versions of the plug-in that match the channel strip input format can be inserted
(mono-to-mono or mono-to-stereo plug-in versions in mono input format channels, for
example).
To insert plug-ins that do not match the channel format
µ
Option-click a channel strip’s Insert slot.
The Plug-in menu displays all formats the plug-in has to offer, rather than being limited
to the matching format. Any down or up mixing that may be necessary happens
automatically.
Working with Plug-ins
Plug-ins are, broadly speaking, broken down into two categories:
• Software instruments, which respond to MIDI note messages
• Audio effects, which do not respond to MIDI note messages
