Percussion instruments are one of the most popular forms of musical expression because they produce loud, distinct sounds. Digital percussion, for example, has become more versatile as a result of technological advancements. Nearly every member of the percussion family, including cymbals, xylophones, and various drums, has been fitted with digital technology. Some forms of digital percussion are controlled by computer software, while others rely on electronic equipment to convert sounds into digital signals. The sounds of digital percussion are contained within small digitized pads in another common form.
Digital technology works with digital signals, which are distinct from traditional signals in that they alternate between two primary frequencies rather than operating on a continuous spectrum. Digital signals are less susceptible to environmental interference, such as static, with this setup.
The majority of percussion instruments can be converted to digital format. A percussion instrument, in general, is any device that makes a sound when struck or vibrated in some other way. Some objects, such as cymbals, may collide with one another. A small stick may be used to hit an object such as a triangle or a xylophone in other types. Drums, which are made up of a thin covering placed over a hollow surface, make up a large portion of percussion instruments.
Drums are the most common type of percussion instrument, and as a result, they are plentiful in digital percussion markets. These are generally cylindrical or rounded objects that make a loud noise when struck. In the case of electric drums, the instruments are connected to other devices such as amplifiers, and sounds cannot be produced without them. Some electronic drums make use of digital technology to create and modify the sounds they emit. Digital electric drums work by digitally processing the sound bites produced when the drum is struck.
Computers provide yet another rich environment for digital percussion. Programs that digitally mimic the sounds of percussion instruments are available in both software packages and on certain websites. MIDI files (Musical Instrument Digital Interface) are a common way to achieve these effects. Many of these programs also include graphic designs of real percussion instruments, such as drums. A mouse pad, keyboard, or even specially attached equipment is usually used to recreate the required percussion strike.
Some digital percussion instruments are also available in the form of small keyboard-style devices. These digital pads typically include speakers as well as various buttons or touch-sensitive areas that a player can press or hit to generate specific sounds. These devices are also versatile, as they can imitate a variety of percussive instruments. They employ the same systems as other digital percussion techniques.
