Be your own DJ with iTunes.
iTunes Integration
djay gives you instant access to all your existing songs and playlists from iTunes. You can browse your music library by Playlist, Artist, Album, Genre, Key, History, and more. Simply drag songs onto the turntables in djay, and they are transformed into virtual records complete with album art.

Automix DJ
Automix your party
One-click, hours of fun. Let djay mix your favorite playlist automatically from iTunes with seamless DJ-style transitions. Using the Automix Queue you can step in any time and queue up tracks on-the-fly.

BPM Sync
Perfectly master transitions
djay’s on-the-fly beat and tempo detection allows you to easily match the BPM of two songs for a perfect transition. Simply press the SYNC button and the two songs are seamlessly aligned.

DJ Set Recording
Record your performance
Capture your mix live — for your latest podcast, movie or photo slide show, or to make a classic “mixtape.” djay saves your performance in high-quality sound files and contains a built-in organizer that allows you to arrange, preview and export your recordings.

Scratch. Mix. Play.
Multi-Touch trackpad control for scratching
djay's dynamic interface elements can be fully controlled with versatile Multi-Touch gestures. Use rotate gestures to adjust the EQ, or two fingers to scratch the record and operate the crossfader.

Zoomable waveforms
Visual mixing with waveforms
djay's advanced audio wave form display gives you an overview of a song's structure and allows you to visually cue to specific points in order to prepare the prefect transition.

Live DJ Sampler
Use the live sampler to add short jingles into the mix. djay comes with a built-in sample pack featuring 20 high quality sounds made by ueberschall, one of the leading companies in the sampling industry. In addition, djay allows you to create your own samples from the turntables or the microphone.

DJ Mixer and EQ controls
3-band equalizers, gain, line faders, and a crossfader give you all the tools you need in a DJ setup to seamlessly blend one song into another.

Harmonic Mixing
Harmonic Match
Finding two songs that complement each other is one of the most challenging tasks when mixing music – for beginners and pro DJs alike. With the introduction of Harmonic Match, djay automatically detects a song’s key and allows to match it to songs of the same key within your iTunes music library. It allows you transpose songs into different keys, and even sort your entire music library by key, perfect for creating studio quality mash-ups of your songs.
