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.
