I need to add that I also own a Novation Remote Zero SL. This is a very cool surface that I use a lot these days. However, I'm now discovering that when both the Remote SL and the TRanzPort are connected, only the Novation operates. If I turn the Novation Off, then the TRanzPort will accept commands. I have no idea why this is. Both are USB devices but I don't remember this happening in Sonar 7 initially. Now, it happens in both Sonar 7 and 8. The TRanzPort receives information on its display indicating that it knows what track Sonar is on even when it won't send mute, solo and arm commands to Sonar, apparently due to the fact that the Novation is also connected. Any thoughts? Kevin
