Just found a solution here (http://duc.avid.com/showthread.php?t=293084)

Ok, I know this post is over a year old , but I wanted to post a fix for this issue incase anyone else found this thread as I did, The problem occurs when your midi device (keyboard) and your digi are trying to control the same thing. For this instance , im using the M-Audio Oxygen 49 and a digi 003. Heres the fix, Open pro tools, in the top menu, select setup, then select peripherals, select the tab "midi controllers" and set all the "type" fields to none, and kablamo !! You're done, This is what worked for me , hope it helps
