Once the Downbeat Marker is created, the Beatgrid will then be created using the BPM value of the track to lay out a series of Bar Markers throughout the track on each bar start.
Each Bar Marker has a Bar number displayed next to the line, these indicate the start of the track’s bar number (i.e. the first beat is the start of bar number 1). If the BPM value is correct, then the Beat Markers will fall on each of the track’s beats.
NOTE: Any bar before the first Downbeat will be shown as negative Bar numbers.
