About Snapping

+

+ There are two ways to think about aligning material to a grid. The first and + most obvious one is where an object's position is clamped to grid lines. In + Ardour, this is called absolute snap and is commonly used when + working with sampled material where audio begins exactly at the beginning of a + file, note or region. +

Beats/N

Set the grid to units of 1/N beats, where N can be 128, 64, 32, 16, 8, 7, 6, 5, 4, 3, 2. The duration of a grid unit will depend on the tempo and meter in effect at that point in the timeline.
-
Beats
-
Set the grid to whole beats. The duration of a grid unit will depend on the tempo and meter in effect at that point in the timeline.

Bars

Markers

Region Starts
-
The grid lines are constructed from region start points (see below).

Region Ends

The grid lines are constructed from region end points (see below).

Region Syncs

The grid lines are constructed from region sync points.
-
Region Bounds

The grid lines are constructed from region start or end points.
