Expert Sleepers Augustus Loop v2.4.1 - Manual (Page 39)

Preferences
Pressing the ‘Prefs’ button brings up a dialogue where various preferences
are set. These global settings are shared by all instances of Augustus Loop,
and are not stored with presets.
The top section shows the product version. The Windows version also shows which SSE
variant has been detected (there are optimised versions of the core processing routines for
systems with SSE2).
The central section will show your serial number once you’ve bought a registration.
MIDI In
This menu controls how the plug-in responds to incoming MIDI CC messages (see below ).
Skin
This menu lets you select a ‘skin’ for the GUI - see the section on skins . Depending on your
host application, the new skin will be applied either when you next open the plug-in GUI,
or when you next load the plug-in itself.
