Snap items to the Piano Roll Editor grid
The Piano Roll Editor has a grid, similar to the Tracks area grid. When Show Advanced Tools
is selected in the Advanced preferences pane, you can set the Snap value for the Piano Roll grid,
independent from the Snap value for the Tracks area grid.
The Snap pop-up menu setting applies to moving, copying, cutting, and resizing note events;
moving, adding, and resizing markers; and setting the cycle area. You can snap notes and other
items using either relative or absolute positioning, and can temporarily override the snap grid,
allowing finer edits and adjustments.
Set the Snap value for the Piano Roll Editor grid
m Choose a value from the Snap pop-up menu in the Piano Roll Editor menu bar:
•
Smart: Edit operations snap to the nearest bar, beat, sub-beat, and so on, depending on the
current ruler division value and the zoom level.
•
Bar: Edit operations snap to the nearest bar.
•
Beat: Edit operations snap to the nearest beat in a bar.
•
Division: Edit operations snap to the nearest division (this is the time signature shown in the
LCD and ruler).
•
Ticks: Edit operations snap to the nearest clock tick (1/3840 of a beat).
•
Frames: Edit operations snap to the nearest SMPTE frame.
By default, the Snap functionality is relative, so that when you move notes or other items, they
retain their relative distance from their original position. You can override relative positioning
with the Snap to Absolute Value option.
Snap to an absolute position
m Choose Snap to Absolute Value from the Snap pop-up menu.
When Snap to Absolute Value is active, moving an event moves it to the exact grid position, not
a relative position. For example, from position 1.2.1.16 to around bar 2 results in it being snapped
to the beginning of the bar (position 2.1.1.1), rather than its relative position (2.2.1.16). Absolute
positioning is useful when you want notes to fall exactly on the beat, but it can result in a more
mechanical rhythmic feel.moving an event
