Apple Logic Pro 9 (TDM Guide) - Manual (Page 23)

This section provides tips and tricks that may be useful when using Logic Pro with
TDM hardware.
As a general working suggestion, you should avoid the simultaneous use of more than
two audio engines in Logic Pro. The strain on the PCI bus can be problematic, resulting
in a number of DAE error messages.
Your first choice should be the DAE—in conjunction with Direct TDM. If necessary, choose
DAE and Core Audio.
This chapter covers the following:
• Importing Native Projects into a TDM System (p. 23)
• System Performance and TDM DSP Usage (p. 24)
• DAE and Direct TDM Bounce Strategies (p. 25)
Importing Native Projects into a TDM System
If you want to use the native processing capabilities of Logic Pro with the project, start
Logic Pro—with the Digidesign Core Audio driver activated.
You will be asked if you’d like an automatic conversion if the project was created on a
non-Core Audio system, provided that the Universal Track Mode setting is the same on
both systems.
You should be mindful of problems that can occur, due to plug-in incompatibilities and
settings that differ between the source and target systems.
If you want to use TDM plug-ins and instruments with the project, you need to load the
project into a DAE/Direct TDM system.
To load a project that originated on a Core Audio system into a DAE/Direct TDM system
1 Deactivate DAE and ensure that Direct TDM is active.
2 Ensure that the Universal Track Mode setting is the same for both Core Audio (on the
project source system) and Direct TDM on your system.
