The vertical lines represent the Step Grid in the Event area.
By default the Step Grid is active and the step size is 1/16th. However you may use another
step size or disable the Step Grid completely, as described below.
Depending on the current zoom factor and Step Grid resolution, if the vertical lines of
the Step Grid are too close to each other they will be hidden to avoid convoluting the
display. For example, this could be the case if you display 6 or 8 bars and choose a
Step Grid resolution of 1/64th.
Regardless of the current Step Grid resolution, the gray lines on the beats (quarter
notes) and the black lines on the bars (notes) are always visible in the Event area.
