# Traktor

Traktor is DJ software developed by Native Instruments. It is also used as a sub-brand for Native Instruments' associated DJ hardware products.

## History

Traktor was first released in 2000. The initial versions available were Traktor DJ and Traktor Studio, with Studio being the version with the most functionality.
Version 2 of the software (known as Traktor DJ Studio 2) was released in 2002. The new features included scratch macros and expanded looping, MIDI, and cue point functionality. Version 2.5, released in 2003, expanded the time stretching functionality, added Open Sound Control (OSC) support, and introduced GUI customization options.
In 2003 Native Instruments expanded Traktor from purely software. They partnered with Stanton Magnetics to develop Traktor Final Scratch: the software for Stanton's Final Scratch digital vinyl system (which used timecode-stamped vinyl records to control MP3s), whilst Stanton developed the hardware. This partnership also allowed Native Instruments to use the Final Scratch timecode functionality in their own Traktor products.
In 2005, Native Instruments added vinyl emulation features to version 2.6 of Traktor DJ Studio, alongside live input, internet broadcasting, support for more file formats, and expanded MIDI capabilities.
Version 3 of Traktor DJ Studio, announced in November 2005, added two more playback decks (for a total of four), built-in EQ & effects, Beatport online store integration, a four-channel mixer. It was re-branded to Traktor 3 on October 11, 2006, when the partnership between Native Instruments and Stanton Magnetics ended. At this point, Native Instruments began manufacturing their own DJ hardware components.
On October 16, 2008, Native Instruments announced Traktor Pro, to replace Traktor 3. It included an updated GUI, revamped effects interface, and updated cueing and looping features.
The subsequent software, Traktor Pro 2 was announced on February 10, 2011, and released on April 1, 2011. New features included multi-channel support and support for a larger number of concurrent loops.
Native Instruments announced in early 2018 that an entirely new version of Traktor (both hardware & software) had been under development. The new version, entitled Traktor Pro 3, was released on October 18, 2018.
In May 2021, a Beta release of Traktor Pro 3.5 added integration with Beatport Link. This new feature allowed DJs to make track selections from Beatport on the fly for the first time.
Traktor Pro 4 was released in July 2024, adding flexible beatgrids, stem generation, the Pattern Player sequencer and Ozone Maximizer limiter.

## Discontinued variations of Traktor

Native Instruments previously offered a lower-priced version of the Traktor software, known as Traktor Duo. Duo featured only 2 virtual decks (compared to the 4 available in the regular version), a single 3-band EQ for each channel, and six effects.
The company have also released Traktor Scratch Pro and Traktor Scratch Duo, which contain the same respective features as their standalone counterparts, along with additional Digital Vinyl System (DVS) functionality, allowing control for timecoded CDs & vinyl.
The entry-level version of the software was known as Traktor LE. It is sometimes bundled with third-party DJ controllers.
A version of Traktor was also available for iOS smartphone & tablet devices. It is known as Traktor DJ.
On August 17, 2010, Native Instruments also released Traktor Pro S4, a new version of the software specialized for their new Traktor Kontrol S4 hardware.
