Ok, I bring in Reason on an instument track record a sound and its fine. I bring another instance in on another instrument track and play it, and it plays the other sound too. Just to test it, I bring up another track (3), play it and it plays all by itself. I go back up to the first track and now 1 and 3 plays together. I go to track 2 and play a note and 2 and 3 plays together. I'm using a Novation X-treme for input. Any input on this would open the gates.
thanks
