Version 5 of Mixed In Key harmonic-mixing software is here, providing DJs the world over with improved features and tools for mixing and mashing up digital music.

As Mixed In Key, the same-named maker of the software, notes, Mixed In Key 5 quickly and accurately identifies the keys and tempos of digital music files, making it easy for DJs to create mashups and play perfect DJ sets. Version 5 offers new features and functions, as well as a powerful new key-detection algorithm.

Mixed In Key 5 offers multi-processor support for both Mac and Windows, allowing the software to take full advantage of the speeds possible on multicore CPUs. Another notable feature is the new Audio Player, which lets users audition the key-detected songs and samples from within the software. In addition to existing support for MP3 and WAV file formats, Mixed In Key 5 adds M4A and MP4 (video file) support.

Version 5's key-detection algorithm provides enhanced levels of accuracy and it can detect key changes within songs. Key changes are clearly shown in the waveform display of the Audio Player, allowing users to see exactly where in the song the change occurs. Whereas the key detection in previous versions looked at a song-file as a single entity, the new algorithm analyzes it as a series of beat-aligned segments. This ability to analyze short audio files means that remixers and producers can use Mixed In Key when working with sample and loop libraries, making it easier to find files in the same key.

The software maintains its use of the “Camelot Wheel” system, which displays key names on a circular chart that is numbered and color-coded. According to the manufacturer, this approach makes harmonic mixing easier by graphically showing which songs are compatible with each other. In version 5, a clickable Camelot Wheel offers a new way to see key-detected material. Once the software has analyzed a collection of songs (for example, an iTunes library), clicking on a key name on the Camelot Wheel instantly brings up a list of all the files in that key, making song selection a snap.

“Mixed In Key 5 is the professional DJ’s choice for harmonic mixing,” said Yakov Vorobyev, President of Mixed In Key. “It’s a powerful DJ tool that connects with your favorite DJ software and DJ hardware, and makes it possible to mix harmonically regardless of your medium.”

With its new feature set, Mixed In Key 5 is more essential than ever when used alongside your main DJ software, according to Mixed In Key. “We love when people use Mixed In Key with Traktor, CD-Js, Serato Scratch Live, and all other DJ and sequencer apps,” says Vorobyev. “It works perfectly with them, and takes your DJ sets to the next level.”

Mixed In Key 5 is now available for just $58. Current users can upgrade from previous versions for $29.99. Learn more at mixedinkey.com.
