The brainchild of Tadao Kikumoto, the engineer behind the Roland TB-303, it features a 16-step step sequencer and a drum kit that, at that time, aimed for realism and cost-effectiveness.

History

As with the TB-303, the realism of the TR-909 was severely limited by technical constraints, and this showed when the machines were released at relatively low prices before its rise in popularity, coinciding with the beginnings of techno and acid. Techno is a form of Electronic dance music (EDM that emerged in Detroit, Michigan, USA during the mid to late 1980s Acid house is a sub-genre of House music that emphasizes a repetitive hypnotic and trance -like style with samples or spoken lines usually used rather than sung lyrics More expensive, sample-based drum computers were better at faithfully reproducing real drum sounds, while the TR-909 sounded synthetic. This synthetic sound was exactly the characteristic that led to the hand-in-hand rise of techno and house music, because the unrealistic, futuristic drum sounds were employed by the Belleville Three.

Juan Atkins, one of the Belleville Three, had already been using a TR-808 while DJing, but moved to the 909, creating beats alongside the music on his turntables at Detroit social-club parties DJed by Deep Space (Atkins and Derrick May). Juan Atkins (born December 9, 1962) is an American musician He is widely credited as the originator of Techno music specifically [1] The Belleville Three were using the TR-909 not only while DJing, but for the production of early techno tracks like Atkins' afrofuturism track "No UFO's. Black science fiction Afrofuturism, or afro-futurism, is an African diaspora cultural and literary movement whose thinkers and artists see Science " Detroit techno was selling well in Chicago, being played alongside Euro synth-pop and "progressive" Italian music, so the TR-909 sound was being played in Chicago even though nobody in Chicago had the machine. However, in a desperate attempt to obtain rent money, Derrick May sold the 909 to DJ Frankie Knuckles, making the 909 a major link between the sound of Detroit techno and the sound of Chicago house music. [2]

"The four-to-the-floor groove and endless snare-roll crescendi ubiquitous in house, techno, and everything that followed come from the [TR-]808 and 909. " [3]

Sounds

The drum kit contains the following sounds:

All drums except for the hi-hats and cymbals are synthetically generated; there is an oscillator circuit with a dedicated filter and envelope curve. A bass drum is a large Drum that produces a note of low definite or indefinite pitch. The snare drum is a Drum with strands of snares made of curled metal wire metal cable plastic cable or gut cords stretched across the a drumhead typically A tom-tom (not to be confused with a Tamtam) is a cylindrical Drum with no snare. This article references the term in the world of music For the term's use in radio and television broadcasting see Rimshot (broadcasting. A clap is the sound made by striking together two flat surfaces as in the body parts of humans or animals A hi-hat, or hihat, is a type of Cymbal and stand used as a typical part of a Drum kit by percussionists in R&B, hip-hop, Disco Cymbals are a modern percussion instrument Cymbals consist of thin normally round plates of various Cymbal alloys; see Cymbal making for a discussion of their A ride cymbal is a type of Cymbal that is a standard part of most Drum kits Its function is to maintain a steady Rhythmic pattern sometimes called a A crash cymbal is a type of Cymbal that produces a loud sharp "crash" and is used mainly for occasional accents as opposed to in Ostinato. A hi-hat, or hihat, is a type of Cymbal and stand used as a typical part of a Drum kit by percussionists in R&B, hip-hop, Disco Cymbals are a modern percussion instrument Cymbals consist of thin normally round plates of various Cymbal alloys; see Cymbal making for a discussion of their Oscillation is the repetitive variation typically in Time, of some measure about a central value (often a point of Equilibrium) or between two or more different states The hi-hats and cymbals are 6-bit samples, compressed and combined with a volume envelope curve (and tuning) to allow slight modification. Thanks to the analog circuitry, various aspects of the drum sound can be modified (pitch, attack, decay). Analogue electronics (or analog in American English) are those electronic systems with a continuously Variable signal

There is also a feature called "accent"—a primitive means of humanizing the drumbeat. In a simplified model of a drummer and a kit, the loudness of the sound created would basically depend on the velocity at which the drummer hits a given part of the kit. A human drummer can emphasize certain notes by playing them louder, and the accent parameter provides a means to boost a particular step. A more complex model would also include timbral change, but reproducing this effect using the TR-909's analog electronics wasn't feasible. In Music, timbre (ˈtæm-bər' like timber, or, from Fr timbre tɛ̃bʁ is the quality of a Musical note or sound that distinguishes different It took the industry a while to even offer this effect in sample based drum machines, due to the price of sample memory and the number of samples one would have to take to faithfully reproduce it.

Part of the charm of the TR-909 comes from its 16-step sequencer — today it might look primitive, not allowing subtle grooves and being limited in variety with only 16 steps, while a more lively, complicated drum pattern might need much more than that. A music sequencer (also MIDI sequencer or just sequencer) is software or hardware designed to create and manage computer-generated music On the other hand, punch the buttons 1, 5, 9 and 13 on the bass drum part, and you have just programmed a four to the floor beat. A bass drum is a large Drum that produces a note of low definite or indefinite pitch. "Four to the Floor" is a hit single by the band Starsailor. While the sequencer is running, a light runs from step 1 to step 16.

Editing

The TR-909 has several editing modes: pattern editing where one focuses solely on the 16 steps, and track editing, which allows for chaining various patterns in a row. Because it has MIDI, it's also possible to control other instruments with the sequencer. MIDI ( Musical Instrument Digital Interface, ˈmɪdi is an industry-standard protocol that enables Electronic musical instruments Computers

This machine and its unique sequencer (both Roland and other manufacturers used either a grid-based sequencer, showing the dots on an LCD, or another method that did not display the pattern at all) were the basis for so-called grooveboxes — self-contained compact synthesizer workstations with rudimentary keyboards and pattern-based sequencers, aimed at creators of electronic music, using sample-based sound generation and a number of realtime controls. Electronic music is music that employs Electronic musical instruments and Electronic Music technology in its production

Other manufacturers have made similar devices:

Not everyone needs the sequencer, so the sounds are also available in convenient 1U-high rack units:

Additionally, a clone of the TR-909's synthesizer parts is available in partial-kit form. The Korg Electribe R was released in 1999 as a dedicated electronic Drum machine to complement the Korg Electribe A bass synthesizer [4] This kit includes the main board and audio out PCBs, sample ROMs, and PIC Microcontroller (for handling MIDI) but requires a builder to order their own components and design their own enclosure.

(Grooveboxes are not included in this list as they contain more than just drums, though they may have copied the principle of the 16-step sequencer. )
