Rewire Sonar X1 and Reason 5 doubling notes

Howdy Gang,

  I'm running Reason in rewire mode. Then I started making a drum track in Redrum and noticed that when I strike keys I'm hearing a doubling effect. As if it's producing the sound 2 times simultaneously.  I'm sure that's a midi channel issue but I've tried a few things and it wont go away. I don't have any problems in stand alone mode. Thanks for any help!
