Appendix F: TDM Mixing and DSP Usage 99
DSP Usage with TDM Plug-Ins
To get the best results when using TDM plug-
ins, keep in mind the following guidelines
 Pro Tools|HD systems use Digidesign’s Multi-
Shell™ technology, that lets any MultiShell
compatible plug-in share DSP chips HD cards.
Up to five types of MultiShell compatible plug-
ins can share a single DSP chip.
 Stereo DSP plug-ins generally use up twice as
much DSP as mono plug-ins.
 Master Faders do not require additional DSP.
Use them freely to control submix levels,
send/bus output levels, and the master output
level of your session.
The session templates provided with your sys-
tem include several useful preconfigured session
setups that make efficient use of DSP resources.
If your computer has unused slots, you can al-
ways increase your available DSP resources by
adding additional HD cards to your
Pro Tools|HD system.
Refer to the DigiRack Plug-Ins Guide for de-
tails on MultiShell plug-ins.
