Devices, systems, and techniques are described for adjusting therapy parameters defining electrical stimulation therapy delivered by multiple electrodes while maintaining a ratio of a value of a therapy parameter between the multiple electrodes. In one example, a device defines a relationship for multiple electrodes that defines a ratio of a value of a therapy parameter between the multiple electrodes. The device performs a master adjustment that adjusts each value of the therapy parameter for each respective electrode of the multiple electrodes by an amount specified by the relationship to maintain the ratio of the value of the therapy parameter between the multiple electrodes. The device controls delivery of electrical stimulation therapy according to the master adjustment.
