The Emagic System Bridge TDM is the ideal link between the DSP world of your TDM system, and your computer's previously unexploited native CPU processing resources. It allows Logic's native audio engine to be routed into the TDM mixer. This enables all Logic tracks, native and VST plug-ins (Mac OS 9) or Audio Unit plug-ins (Mac OS X), including Audio Instruments, to be used in conjunction with your TDM system DSPs. ESB TDM also enhances the functionality of the EXS24 by allowing it to be inserted into the Aux channels of Logic Platinum's TDM mixer.
