About
Mixxx is a powerful, free, and open-source DJ software application designed for performers ranging from bedroom beginners to experienced turntablists. Available on Windows, macOS, and Linux, it provides a comprehensive suite of mixing tools with no cost or subscription required. At the core of Mixxx is its BPM and musical key detection engine, which helps DJs identify compatible tracks from their library instantly. The Sync Lock feature enables seamless beatmatching across up to four simultaneous tracks. The built-in effects engine encourages creative sound design with support for chaining multiple effects and real-time parameter control. Mixxx includes extensive DJ controller support with built-in mappings for popular MIDI and HID hardware, and a programmable mapping system lets users customize controls to fit any workflow. Vinyl enthusiasts can connect turntables with timecode records to scratch and manipulate digital audio files as if they were pressed on vinyl, thanks to the vinyl passthrough mode. The integrated music library handles metadata, BPM tags, and key information to streamline track management during performance. Developed by an international community of passionate DJs and programmers with no corporate backing, Mixxx is committed to remaining free forever. Contributors can get involved through bug reporting, controller mapping creation, translation, or direct code contributions on GitHub. Whether performing live at venues, internet broadcasting, or honing skills at home, Mixxx offers a fully featured, accessible platform for digital DJing.
