In Piano Roll View, when I want to change the note velocity dragging the mouse, Sonar plays the note only at the current velocity, when I click the mouse over the velocity control.
After moving up or down, if I want to know the sound result, I'm forced to click again on the velocity control.
I would like to know if there is any setting in Sonar that allows to hear all the velocity variations of the note DURING the drag-and-drop process.
See this example (Pro Tools):

This is much easier to check the final result with just a mouse movement, instead of clicking several times until you discover the velocity you want ...

Thank you!
Just one more thing: unlike the sample video above , which Pro Tools plays the note at each velocity change, I noticed that Sonar plays the velocity apparently at 120 BPM (regardless of the current metronome and velocity changes). Is this the only way? Not ideal, but it helps.
