A system and method using a plurality of electrodes. An immediate virtual multipole is defined, an immediate electrode configuration emulating the immediate virtual multipole is defined, electrical energy is conveyed to the electrodes in accordance with the immediate electrode configuration, a new virtual multipole is defined by changing a parameter of the immediate virtual multipole by a step size, a new electrode configuration that emulates the new virtual multipole is defined, a difference value as a function of the immediate virtual multipole and the new virtual multipole is computed, the different value is compared to a limit value, electrical energy is conveyed to the electrodes in accordance with the new electrode configuration if the difference value does not exceed the limit value, and the absolute value of the step size is decreased to create a new step size if the difference value does exceed the limit value. |
