Djay (software)
# Djay (software)

djay is a digital music mixing software program for Mac OS X, Microsoft Windows, iPad, iPhone, and iPod Touch created by the German company algoriddim. It allows playback and mixing of digital audio files with a user interface that tries to simulate the concept of "two turntables and a microphone" on a computer. Before the commercial release in November 2007, djay had initially been released as freeware in June 2006. In December 2010 the software was also released for the iPad, and subsequently for iPhone and iPod Touch in March 2011.

Its interface consists of two turntables, a mixer and a music library showing songs and playlists from iTunes. It no longer supports Spotify integration.

djay for iPad received an Apple Design Award in 2011.

## Features

### iTunes integration

djay's iTunes integration allows the user to mix songs directly from the iTunes library. It provides the option of browsing the library, for example by Playlist, Artist, Album, Genre, Key or History. Dragging songs onto the turntables in djay, transforms them into virtual records complete with album art.

### Automix

Automix mode enables djay to automatically mix songs from the iTunes library, and play them instantaneously with DJ-style transitions. Using the Automix Queue the user can step in any time and immediately queue up tracks.

### Transitions

djay's instantaneous beat and tempo detection allows the user to match the BPM of two songs for a transition. On pressing the SYNC button the software automatically syncs the BPM of the two songs so that both are smoothly aligned.

### Record live performance

djay allows the user record live mixes and save them in high-quality sound files. It also contains a built-in organizer arranges, previews or exports the recordings.

### Multi-Touch trackpad control

Mac has a tool called the Multi-Touch trackpad. djay can dynamically utilize this trackpad to fully control the software with versatile Multi-Touch gestures. For example, a rotating gestures can adjust the EQ, while two finger swipe gesture can scratch the record and operate the crossfader.

### Live sampler

There is a built-in sample pack featuring 20 high-quality sounds made by ueberschal, a company in the sampling industry. In addition, djay allows the user to create custom samples from the turntables or the microphone.

### Mixer and EQ controls

### Beat-matched looping & cue points

djay has a range of different looping styles: Auto, Manual and Bounce. The use can manually set loop in and out points, use Auto-Loop to continuously loop part of a song, or remix live using Bounce-Loop to mash up the song, all in perfect sync with the beat.

### iCloud integration

The program can work with iCloud (and iTunes Match), meaning the user can sync it with the iTunes library in the cloud. In other words, tunes are synced between every iOS device connected on the cloud. All of these devices can run djay, and cues and BPM information edited or added in will appear immediately in all of the others. There is a remote control available for iOS to control the djay app on the MacBook over WiFi.

### Pre-cueing
