A drum machine, sometimes called a rhythm machine, is an electronic, digital drummer. Smaller and lighter than a VHS tape, the drum machine comes with various repeating drum patterns and styles to serve as the backbeat for everything from hard rock to jazz, pop, funk, salsa and hip hop. Tempo or beats per minute (BPM) is adjustable, and some drum machines also include percussion sounds.
Like most digital devices, the drum machine has a LED screen for cycling through "patches" or tracks named according to music genre. "Hard Rock" might be one category, with 10 or more track variations called HR-1, HR-2, HR-3, and so on. Each track within the category will differ from the others in some way. One might use the kick drum on an extra beat, while another might include toms or a cymbal ride.
Preset patches offer the user a wide variety of ready-made choices. Switching to another genre or category offers a whole new set of relative choices. A drum machine can come with several "drum kits" that each have their own "voices" or effects. Other handy patches of the drum machine include beginnings, breaks and endings. These can be stitched together with the standard patterns to preprogram an entire song -- a great tool for soloists and songwriters.
Many models come with pressure-sensitive pads for finger drumming. Pads are each assigned a drum sound, such as bass, kick, snare, hi-tom, low-tom, cymbal crash and more. Play for fun or record your patch to digital memory for later use. You can even record an existing patch while adding your own sounds to it, making tracks customizable.
A drum machine might also include a synthesized bass guitar track. Bass "voices" or effects can include slap, finger, pick, synth and acoustic. It's easy to practice your chops or write original songs while playing with a "trio." Some drum machine models allow you to enter chord progressions to automatically transpose the bass so that it will play along with you, rather than the other way around. This is another great feature for songwriters putting together a demo or recording tunes for their own pleasure.
Drum machines do not have speakers, but feature a wide variety of inputs and outputs. The headphone jack along with the ¼" mono-in for guitar will allow you to play for hours without disturbing the household or neighbors. Line-out can be used for external amplification, to run to a recording system, mixer or other device. Connections vary between models but many also include a MIDI jack.
The drum machine is a basic tool for any guitarist, worth its weight in gold for its ability to provide great sounding drum tracks anytime, anywhere. Practice is much more enjoyable and interesting when playing with a drum machine, and songwriting becomes more inspired. A drum machine is a great gig tool. Program it to accompany your set at the local club.
Drum machine features vary widely, so if a particular function is important to you, be sure it is included before buying. A basic model starts at less than US$200, but drum machines are also integrated into many other devices, including digital effects processors and personal recording studios. If you will be acquiring one of those in the near future, you might save money by looking into those devices as well.
Frequently Asked Questions
What is a drum machine and how does it work?
A drum machine is an electronic musical instrument designed to imitate the sound of drums, cymbals, other percussion instruments, and often basslines. It works by allowing users to program rhythms and patterns that can be played back with the touch of a button or sequenced into a song. Modern drum machines offer a range of sounds that can be tweaked and manipulated, providing a versatile tool for music production and live performances.
Can a drum machine replace a live drummer?
While a drum machine can replicate many of the sounds a live drummer produces, it cannot fully replace the human feel and dynamic expression of a live drummer. However, for certain music styles or practical scenarios like home recording or small venues, a drum machine can be a suitable alternative, offering consistent timing and a wide variety of sounds.
What are the benefits of using a drum machine in music production?
Drum machines offer several benefits in music production: they provide a consistent tempo, a diverse range of sounds, and the ability to easily edit and manipulate rhythms. They are also compact and portable, making them ideal for producers on the go. Additionally, drum machines can facilitate experimentation with complex beats that might be difficult for a human to play, expanding creative possibilities.
How has the drum machine evolved over the years?
The drum machine has evolved significantly since its inception. Early models in the 1930s and 1940s were rudimentary rhythm devices. By the 1980s, machines like the Roland TR-808 and TR-909 became iconic for their distinctive sounds, which shaped various music genres. Today's drum machines are sophisticated digital devices with vast sound libraries, touch-sensitive pads, and integration with computer-based production software.
Are drum machines only used in electronic music?
No, drum machines are not exclusive to electronic music. They have been used across various genres, including pop, rock, hip-hop, and R&B. Artists and producers value drum machines for their versatility and the unique texture they can add to a track, regardless of the musical style. Their use in mainstream hits across the decades showcases their cross-genre appeal.
