From Native Instruments:
Traktor Pro is the latest version of the leading digital DJ software, offering four full-featured playback decks, an integrated DJ mixer with studio-quality EQs and filters, 28 flexible performance effects, automatic beat-matching and intuitive control functions that accommodate DJs of all styles and experience levels.
All crucial performance functions like cueing and looping have been revised and refined for intuitive handling in Traktor Pro, while extensive cover artwork support allows users to visually browse their music library in an especially efficient way. Advanced syncing functions give DJs more time to focus on the creative aspects of their performance. Precise beat grids are created automatically for all tracks, and the "Sync Lock" function makes sure that even multiple decks and tempo-synced effects never drift out of sync.
Traktor Pro also opens up vast new possibilities for creative sound manipulation, with a powerful performance multi-effects section that is both extremely versatile and highly accessible. And to give users the maximum level of control over their performance, Traktor Pro offers state-of-the-art MIDI controller integration, and comes with mappings for all relevant DJ controllers on the market.
The two-deck "Traktor Duo" version provides most of the powerful features of Traktor Pro at an even more affordable price, offering an ideal entry into the world of digital DJing.
What's new in this version:
Version 1.2 adds two additional multi-effect sections, three new creative effect algorithms, improved studio-quality time-stretching as well as various usability and performance enhancements.
