NoiseBursts_PT 9 and Reaper via Rewire

Hello all



I'm running a copy of Reaper as a Rewire slave to a Pro Tools session.



I have about 3 or 4 Pro Tools sessions running like this where I've been using "Save As"

to create new Reaper Sessions to run alongside PT.



I'm using Reaper as a way to host VI's, mostly Kontakt 5 as a VSTi with 64 Out



In each session , about halfway through playback I'm getting some digital static noise

and the Midi Beat Clock gets disrupted as my Virtual Instruments in Reaper lose their tempo / clock from Pro Tools.



Anyone else encounter this and find any fixes or work arounds ?



Here are my system details:



2009 Mac Pro 4,1 Quad Core

OS 10.6.8

Pro Tools 9.0.6

DigiRewire 9.0.6

Reaper v4.611

Kontakt v5.2.16382



Any suggestions are appreciated !
