Mixxx 2.4 Released

Fri 16 February 2024 Mixxx Team release announcement, 2.4

We are proud to announce Mixxx 2.4, a new major version of our free open source DJ software, available right now. It's been two years since the last release due to the large number of great new features and important changes under the hood. See the changelog for the full list of changes.

The 2.4 release includes the following highlights:

EngineOS Export

Mixxx 2.4 adds support for exporting crates, playlists and the library to Engine DJ OS devices, including Denon and Numark standalone controllers.

This allows users to prepare their tracks on a laptop using Mixxx and export them to a USB stick for use on a standalone controller at their gig.

Saved Loops

Mixxx 2.4 adds support for Saved Loops, which can be assigned to any Hot Cue slot. If you already have tracks from Serato DJ with Saved Loops, Mixxx 2.4 will import them automatically.

Effect Chains

Mixxx 2.4 introduces Effect Chains, a set of effects which can be saved and reloaded with all their parameters and individual Meta Knob mappings. Effect Chains can also be exported and imported, which allows you to share them with other Mixxx DJs. Once you've created an Effect Chain, you can create a custom Super Knob mapping which turns the chain into a Quick-Effect, where you take creative control with a single knob. Effect parameters can be reordered and or hidden. In the effect units, Mixxx 2.4 also displays the value and unit of effect knob parameters while they are being adjusted.

Track Menu Enhancements

The track menu in Mixxx 2.4 is enhanced by several new features:

• Select loaded track in library.
• Analyze/re-analyze with variable/constant BPM on a per-track basis.
• Look up track metadata at Discogs, SoundCloud and LastFM.
• Remove track files from disk.

Sync Lock Improvements

Mixxx 2.4 adds support for manually selecting the Sync Leader by clicking on the new button with the crown symbol next to the Sync button. This mode is useful when tracks have variable BPM. All decks with sync enabled will follow the changing BPM of the Sync Leader.

Many Other Changes

Soundstretcher / Key-Shift Algorithms

Mixxx 2.4 now supports three different key shift algorithms:

• Soundtouch (Basic audio quality - medium CPU usage)
• Rubberband R2 (Good audio quality - higher CPU usage)
• Rubberband R3 (High audio quality - very high CPU usage)

Waveform Rendering Reworked

The waveform display has been rewritten, solving some longstanding performance issues, especially on macOS.

Apple Silicon Support

Mixxx now supports macOS ARM systems ("Apple Silicon") such as M1 natively and provides installation packages for those architectures. For macOS users, this increases the stability and performance of Mixxx on Apple silicon.

Controller Backend

Modernized Javascript ES7 based controller mapping system. HID backend rework.
