Emagic Host TDM Enabler runs the virtual Intruments on your Mac's CPU but sends the Audio stream to TDM mixer via DirectConnect where it can be mixed & processed with the rest of your ProTools Session.
You will need an White Apple XSKey to run these.......

Unfortunately the Host TDM Enable were dropped during the switch to Intel processors
The Host TDM Enabler can be used up to ProTools 7.4.2 on a PPC Mac only
You need the OSX installers for that. I did not upload them as this is a OS9 forum
but if anyone needs them let me know.

You get 5 of the Logic Virtual Intruments:

1) ES-1
2) ES-2
3) EVP-88
4) EVD-6
5) EVB-3

Attached is a Picture showing ES-2 using DirectConnect on the DSP chip in ProTools.
This is for ProTools 5.1.3. Also attached are the installer files verion 1.0 & 1.1 update

Note 1:
You will need the latest version of DirectConnect installed 5.1.1cs10
Attached as well. You will need to manually move the updated files to your system folder & DAE plugins folder
Be sure to remove the older versions as the name of the files are different.

Note: 2:
Space Designer may have been added to the TDM Enabler as an update when Logic Pro 7 came out
It's for OSX only...... sorry folks. I cannot confirm as I don't have an OSX setup to test this.

Note 3:
This is for ProTools 5.1.3 Users on OS9 and does nothing for Logic
