Disregard my prior post based on misinformed forum knowledge across the web about pro tools. LOL. lesson learned.
I contacted the instructor i had for my prior pro tools certification level 101 and 110, and here is what he recommended for a mac, but hes getting back to me about doing it on a PC:
Open a Pro Tools session
Create an instrument track and place the Virus plug-in on the insert
create your MIDI performance on the Instrument track.
Open up AMS via Pro Tools Setup>MIDI>MIDI Studio, or open from your utilities folder on the Mac
Switch to the MIDI Devices Tab, and double click on the IAC Driver
Check the Box that says "Device is online"
Click the "More information" arrow if you don't see the ports
In the ports section add two ports, one called Reaktor In, and the other Reaktor Out
Close the IAC Driver Properties window
Quit AMS, as you are done with it.
Open up the stand alone version of the Reaktor application
Load your ensemble patch
In the System menu of Reaktor choose Audio+MIDI settings
switch to the MIDI Tab
In the Input interface section switch IAC Driver "Reaktor In" On
In the output interface section switch the IAC Driver "Reaktor Out" On
Click OK to close the box
Choose View>Show Toolbox
Play the Reaktor sequence and ensure the little MIDI out light in this box flashes to show MIDI output
Open the Ensemble-Structure window and delete the audio outputs by clicking on them and hitting delete.
Leave the Reaktor application running and Switch back to Pro Tools.
From the Pro Tools menu choose Setup>MIDI>MIDI Beat Clock
Make sure the box "Enable MIDI beat clock for..." is checked
Check the box that says IAC Driver, Reaktor In
You have now successfully linked the two transports together. If you play Pro Tools, Reaktor should play, and also will follow what ever tempo Pro Tools is running at.
Now for your Reaktor to control the Virus plug-in, all you need to do view the instrument portion of the Instrument track in Pro Tools, and change the Input of the MIDI portion of the instrument track to Predefined IAC Driver, Reaktor Out "All Channels"
Any MIDI data Reaktor spits out will now affect the Synth on that track.
(Now I gotta find out how this is done on a PC.)
