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 + Edit > Preferences > User Interaction
+ 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

+ Holding down the snap modifier will disable the current grid setting and allow you to move the object freely.

Syncing Regions to the Grid

Select the region(s) and press V. This will set the sync point to your edit point.
