+ If the surface is using <code>/strip/list</code>, the surface needs to know
+ if the strips have changed. This would be true if a strip gets moved, created or
+ deleted. When this happens Ardour sends <code>/strip/list</code> to the surfaces
+ that have previously requested a <code>/strip/list</code>. This lets the
+ surface know that it's list of strips is no longer valid.
