behave. You can modify the grid units to fit your needs.
+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.
+ The second, relative snap, is used when an object's position
+ relative to the grid is important. In music, this allows you to
+ move objects around without changing the "feel" (or timing) of a performance.
+ Relative snap is the default method of snapping in Ardour.
+ While dragging objects you may switch from relative to absolute snap by
+ pressing the absolute snap modifier key(s).
+ You may also disable snap entirely by using the snap modifier.
+ The absolute snap and snap modifiers (along with other modifier keys) may be set in
+
+ For common use patterns, it is recommended that you assign a unique key for
+ one snap modifier and two keys for the other in such a way that they share an otherwise unused key.
+ For example, you may choose the snap modifier to be the key and the
+ absolute snap modifier to be and , .

Snap Modes

+Using the above types, Ardour supports three different modes of snapping to the grid:

+ object to reach the same relative position on the next grid line.
+ Sometimes you may wish to place an object exactly on a grid line.
+ In order to do this, use the "snap to absolute" modifier.
+ When holding down this modifier during a drag, the dragged object will jump
+ to the grid lines rather than maintaining its original distance from the line.
+ New objects will always be created at grid points.
+ Holding down the snap modifier will disable the current grid setting and allow you to move the object freely.
- is a less strict type of snapping. Objects can still be moved to any

+ In order to move an object very close to a snap point, it may be necessary
+ to zoom in to prevent snapping to that point, or to use the snap modifier to disable snap completely.
+ As with Grid mode, both the snap modifier and absolute snap modifiers function in this mode.
Syncing Regions to the Grid
- By default, a region's beginning will snap to points along the timeline,
+ By default, a region's beginning will be used as the reference for both types of snapping,
but you can change this behaviour by setting a sync point in
the region. Select the region(s) and press V. This will set
the sync point to your edit point.
