Imagine you have a block of 1024 samples, and at sample 24 a control  
value changes from 1 to 2, you could do:

    plugin->port = 2.0;

which puts the control value change in slightly the wrong place, or  
you could do: (chopping)

    plugin->port = 1.0;
    plugin->port = 2.0;

It's not a technical term or anything, I just needed a word :)
