When the number of beam elements to be changed is very large, this can introduce
a significant overhead on the simulation time. For these cases it is possible to use
the :class:`xtrack.MultiSetter` class, to perform the changes in a more efficient way,
bypassing the expressions and acting directly on the element properties.
Furthermore, the MultiSetter stores the
memory addresses of the quantities to be changed and performs the changes with a single
compiled kernel, using multithreading when allowed by the context.
The following example shows how to use the MultiSetter to apply a sinusoidal
ripple to the strength of several quadropoles of a synchrotron.
