Electronic drum module

An electronic drum module is an electronic or digital music device in an electronic drum kit that serves as the central processing unit and sound module. The drum module creates or produces the drum kit sounds or other sounds selected by the drummer. By itself, a drum module cannot play or sound drum beats. It only produces drum sounds when a performer strikes electronic drum pads or acoustic drum kit instruments that have electronic "triggers" attached to them. When the electronic drum pads or trigger-equipped instruments are struck, this sends a signal to the drum module, which produces the corresponding electronic drum sound. Even when drum pads and/or triggers are connected to a drum module, the drum module by itself does not make any audible sound. Like other electronic instruments such as the synthesizer, the drum module only outputs an electronic signal. The performer can hear this signal by connecting headphones to the drum module or by plugging the drum module into an amplifier and loudspeaker or PA system for audible practice or live performances. The drum module's output signal can also be patched into an audio console for concerts or sound recording. The nomenclature varies. For example, electronic drum modules are called "percussion sound modules" in the case of Roland Corporation, or sometimes simply modules. A common colloquial term for this device is drum brain..
