And last but not least Emagic System Bridge (ESB)
You will need an White Apple XSKey to run Logic this way
This is built into Logic an all the files needed are included in the installers for Logic Pro/Platinum
It's important to install your ProTools system first and have it functioning so that the Emagic installers
see the additional hardware to install all the support files.
The Emagic System bridge will allow you to Bus the whole Native side of Logic into TDM side.
Meaning both are running side by side as one big mix going thru your ProTools TDM hardware.
So you get the best of both world and this is way to get the most horsepower out of a DAW.
You can process tracks or instruments Natively using all Logic plugins or VST/Audio Units
sending up to 8 channels to TDM Aux busses. At the TDM aux busses you can load any TDM plugin for additional processing. In short it's an 8 channel sub mixer to TDM hardware.
In addition:12 Stereo instances of EXS-24 Samplers can be routed to Aux TDM channels for further processing
The ESX-24 processing is still calculated on your Mac's CPU
NOT the TDM chips.
Attached is a Picture of a my mixer in Logic where I loaded an VST Instrument (B4) and I'm sending it to a TDM Plugin (TC Megaverb). If you look at the TDM system usage you can see that ESB is just sending it's ouput via DirectConnect . The other screenshot is the settings for ESB in the driver section of Logic.
Note 1:You cannot process TDM tracks with Native plugins and ESB is inside of Logic and does work for ProTools, Cubase or Digital Performer
Note 2:Logic supports ESB on ProTools Mix & HD hardware up until version Logic pro 9.1.5 Intel/PPC
Note 3:To use Audio Units you must be using a OSX version of Logic
Note 4:On an Intel Mac (Mac Pro) ESB will only work with a PCI Expansion chassis using OSX 10.4.11 or lower
so that means if you have an expanded Protools rig inside of a chassis connected to an Intel Mac Pro you must use Logic 7.2.3 on Tiger 10.4.11 If you do not use an PCI Expansion chassis then ESB works fine.
PPC Macs (G4 or G5) seem to be unaffected so you could run Logic 9.1.5 on Leopard 10.5.8 with a 7 card TDM system inside of a PCI expansion chassis and ESB works fine.
