In the bottom third, there is a vertical line for each bar. The shorter lines represent one
beat, but are not always visible (depending on the zoom setting).
Start and End Markers
The song start point is normally at position 1 1 1 1. You can move the song start point
to an earlier position for playing upbeats or program change commands, by grabbing
and dragging it with the mouse. The position display in the top left of the window will
indicate where it is. The song end (default: bar 201) can be set using the same method,
or with the numerical Song End display (see “MIDI Monitor/Song End” on page 93).
In folders, the start and end markers refer to the folder rather than the song. The length
of a folder can also be adjusted from within the folder itself.
Song Position Line
The Song Position Line (SPL) is a vertical line which indicates the current song position
in all horizontal, time-based windows. You can grab the line with the mouse, and drag
it to the desired position (but only if there is no Region or event at the mouse position
when you drag it). Selecting Wide Song Position Line in the Preferences > Display >
General page switches to a thicker SPL.
Direct Placement
As it can be difficult to grab the SPL in the window itself, you can also directly position
it by using the bottom third of the Bar Ruler. Just click at the desired position in the
lower third of the Bar Ruler to make the SPL jump to the point you’ve clicked.
Double-clicking on the bottom third of the Bar Ruler repositions the SPL, and also
toggles between playback (or record) and stop modes.
