Sonar 8.5.3: I just rehearsed a video tutorial about velocities and in the middle of my talk, I show the file - none of the velocities are displayed any more. They were there a minute ago. 
 
I'm in the Piano Roll View with the Controller Pane open and set to Notes/Velocity and there's nothing there. Can anyone tell me what happened and how to get it back?
 
Thanks - rev
 
(I tried closing without saving and reopening but the display of velocities is still not there)

Check the "velocity" option in the context menu (upper left corner).
 
If you uncheck the "show notes" option, the velocity selection also gets unchecked. If you then re-enable the "show notes" option, the velocities option is not automatically re-enabled.
