Electronic drums


An electronic drum, also known as digital drums or digital percussion, is a modern electronic musical instrument, a special type of synthesizer or sampler primarily designed to serve as an alternative to an acoustic drum kit or other percussion instruments. An electronic drum consists of an electronic or digital sound module which produces the synthesized or sampled percussion sounds and one or more electric sensors to trigger the sounds. Like regular drums, the sensors are struck by drum sticks or by the hands (depending on the type of drum pad) and they are played in a similar manner as an acoustic drum kit.

Strictly speaking, sequencers playing pre-programmed electronic drum tracks and electronic or digital drum machines are not electronic drums, because a drummer or other musician is not triggering the sounds.

The electronic drum (pad/triggering device) is usually sold as part of an electronic drum kit, consisting of a set of drum pads mounted on a stand or rack in a configuration similar to that of an acoustic drum kit layout, with rubberized (Roland, Yamaha, Alesis, for example) or specialized acoustic/electronic cymbals (e.g. Zildjian's "Gen 16"). The drum pads themselves are either discs or shallow drum shells made of various materials, often with a rubber/silicone or cloth-like coated playing surface. Each pad has a sensor that generates an electric signal when struck.

The electric signal is transmitted through cables into an electronic or digital drum module ("brain" as it is sometimes called), synthesizer or other device, which then produces a sound associated with, and triggered by, the struck pad. The sound signal from the drum module can be plugged into a keyboard amp or PA system for use in a live band performance or listened to with headphones for silent practice. Since digital drums have become more popular, companies have started selling digital electronic drum files, referred to as drum kits. While electronic drum kits are typically used to trigger drum and percussion sounds, a MIDI-equipped electronic drum kit can be used to trigger any types of MIDI sounds, such as synthesized or sampled piano, guitar, or any other instrument.
