Abstract: A system includes an apparatus and a processor. The apparatus includes a set of actuator elements that move between two positions. Each actuator element is comprised in: exactly one first subset out of a plurality of non-empty first subsets and exactly one second subset out of a plurality of non-empty second subsets. The processor is configured to generate one or more control commands for a group of subsets out of the first and the second pluralities of subsets in response to a number of moving elements which, if released from the first extreme position during a second sampling cycle, enables production by the apparatus during the second sampling cycle of a sound.
