I'm trying to confirm X2/X2a GUI behavior for the SELECT buttons on both the Mackie MCU and the Mackie d8b + D8Bridge control surfaces. Since installing X2 and X2a my control surface (Mackie d8b + D8Bridge) SELECT buttons no longer highlight/select the corresponding track on the Sonar X2/X2a GUI. The VFD display on my control surface does momentarily report the full track name corresponding to the SELECT button track, but there's no indication in the Sonar X2/X2a GUI that the track has been selected. I'm nearly certain that the control surface SELECT buttons highlighted/selected the corresponding track in Sonar Producer 8.5.3. If you're using either the Mackie MCU or the Mackie d8b + D8Bridge control surface with X2/X2a, would you please post your Sonar X2's/X2a's GUI behavior in response to a SELECT button press on your control surface. I'd like to know whether this is peculiar to my rig or if other users are experiencing the same issue. Thank you!
