An electronic drum is an electrical device struck by a drummer, played in real time (using either hands, sticks, brushes or other implements) to produce a selection of sounds, instruments and effects, from either samples or modeled sounds contained in a processor or drum module. Some would designate it an electronic synthesizer that can, with developments in the last decade, replicate the sound of an acoustic drum kit credibly and with good quality. Strictly speaking, according to a somewhat narrow definition, sequencers and drum machines are therefore not actually an electronic drum.
