Apple Logic Pro 7 Manual Do Utilizador

 

 

 

In general, DAWs take one of two approaches for the task 
of audio signal processing: the use of dedicated 
hardware DSPs (TDM systems), or the native processing 
capabilities of the computer’s CPU.

 

Logic Pro allows you to make use of your TDM system DSPs in conjunction with your 
computer’s native CPU processing resources. 

The link between the DSP world of your TDM system, and your computer’s native CPU 
processing resources is the ESB TDM (Emagic System Bridge TDM).

The ESB TDM allows your computer’s CPU to processes one audio engine (Direct TDM), 
and the DSP of the TDM hardware to processes another (DAE). This is done by using 
two different mixers in Logic’s Environment:  A TDM Mixer (using the DAE) and a native 
mixer (called the DTDM Mixer). The first one handles TDM plug-ins, while the other 
works with native plug-ins in both Audio Unit and Logic formats. 

Up to eight of the DTDM Mixer outputs can be routed into the TDM Mixer. The output 
signals are received by the virtual ESB TDM inputs—chosen as Inputs on the TDM Aux 
Objects. This enables all Logic tracks, native and Audio Unit plug-ins—including 
software instruments—to be used in conjunction with your TDM system DSPs. 

The output of the TDM mixers is fed via connected Digidesign TDM hardware. 

 

About This Guide

 

This guide will introduce you to all that you “need to know” to get your TDM hardware 
up and running with Logic Pro. 

We will also introduce you to the ESB TDM and EXS24 TDM. These expand and enhance 
the flexibility of your Logic and DAE/TDM production system.

Further to this, you will also learn about importing and exporting audio between the 
Logic and Pro Tools software.
