Load Setting
 
Loads stored parameter settings from disk. The file selector box only shows settings for 
compatible plug-in types. It can also read the Digidesign format for TDM plug-in 
settings.
The parameter settings of a plug-in can also be copied between the plug-in’s mono 
and stereo versions, and the Digidesign format for plug-in settings can be read (the 
supplied settings of most plug-ins are saved in this format). Logic automatically 
displays the corresponding files in the file selection box when loading settings via the 
Settings menu of Plug-in windows. Settings files are usually located in a 
 
Settings
 
 folder, 
within the 
 
OS X Library/Application Support/Digidesign 
 
folder. The name of the most 
recently chosen setting is indicated by a dot in the menu listing.
 
Support of TDM Plug-in Side Chains
 
In applicable TDM plug-ins—Compressors, Noise Gates, Vocoders, and so on—you can 
select a different source for the side chain input (or key input). You can choose a side 
chain input source from all tracks, busses or inputs.
 
RTAS Plug-ins
 
Please note that RTAS plug-ins are not supported by Logic Pro. Logic Pro only supports 
Audio Unit, TDM, HTDM, and the native Logic plug-ins supplied with the software. 
If you currently own any RTAS plug-ins, you should install the HTDM or Audio Unit 
equivalents for use in Logic. Most plug-ins are available in several formats.
If no Audio Unit version is available on your RTAS plug-in installation CD(s), please visit 
the website(s) of the plug-in manufacturer(s).
 
Specific Characteristics
 
Please note the following if you want to make use of your hardware’s TDM functions 
with Logic Pro:
 
Deleting Objects
 
If you delete an Audio Object in the Environment, by selecting it and pressing 
Backspace, the level of this Object will be set to zero (minus infinite dB). Output or Bus 
Objects, however, are an exception:  When deleting these, the level will be set to 90 
(0 dB); if they weren’t, the tracks routed to this Output would not be audible. The other 
settings (send paths, plug-ins, and sound control) are not deleted, but are merely 
muted. This way, Logic automatically ensures that DSP processor capacity isn’t wasted. 
As soon as the Object is re-displayed in the Environment, the most recently used level 
will be restored. In the TDM system, the send and plug-in will be restored.
