Logic Pro 8 TDM Guide
In general, DAWs take one of two approaches to audio signal processing: the use of
dedicated hardware DSPs (TDM systems), or the native processing capabilities of the
computer CPU.
Logic Pro allows you to make use of both your TDM system DSPs and the 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.
The ESB TDM allows your computer’s CPU to process one audio engine (Direct TDM),
and the DSP of the TDM hardware to process another (DAE). This is done by using two
different mixers in Logic Pro: 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 in to the TDM Mixer. The output
signals are received by the ESB TDM inputs—using TDM aux channel Input slots. This
enables all Logic tracks, native and Audio Unit plug-ins—including software
instruments—to be used in conjunction with your TDM system DSPs.
This guide will introduce you to all that you “need to know” to get your TDM hardware
up and running with Logic Pro 8. It will also introduce you to the ESB TDM and
EXS24 TDM.
The use of Logic Pro 8 functions is discussed in the Logic Pro 8 User Manual.
