- Sampler
The Sampler is a very powerful tool that allows you to create, play and loop short sound snippets. With these short sound clips, you can either make entirely new music or simply integrate them into the main mix. To create and build your own collection of samples, you can record individually from Turntable 1, 2 or the Microphone. The Sampler has a highly precise recording timing which can be used to extract a particular fraction of a song, similar to how you would use a "trimmer" in audio editing applications.

- Full Screen
Breathtaking graphics and animations become even more immersive in djay 2.0's new full screen mode.
You can optionally show/hide the music library in full screen mode.

- Automix
Let djay be your DJ!
With Automix, djay will automatically mix live any iTunes playlist of your choice with amazing transitions.
Simply press the Automix button to get the party started!

You can even use Undo/ Redo as a fun mixing tool to switch between two states. For example, Bass On - Bass Off or skipping the needle back and forth.

- Saving Song Settings
djay 2.0 allows you to save all slider settings you have made for a song such as EQ, Speed, Balance, Pitch and Gain.
You can instantly save the settings for a song without modifying the original sound file and the settings will be applied the next time the song is loaded into djay.
You can also save any Cue Points, BPM and Loop region that you created for a song.

- Efficient audio file seeking capabilities
djay 2.0 offers highly innovative ways of seeking through your sound files to find a precise spot in a song or to analyze a song's structure.

- Enhanced Music Library features
djay's iTunes integration has dramatically improved. You can now arrange tracks by Playlist, Artist, Album, Genre and Composer. The tracks table contains a very useful status column that indicates whether a song is currently loaded on a turntable, if it has already been played, and various other information.
The new Song Marking feature allows you to visually mark any songs in your library so you can easily find them later during a djay session. The Song Info viewer gives you a detailed overview about each song.

- History of songs
djay now allows you to keep track of all the songs you have played during a djay session. You can even export your song history as a playlist to iTunes or save it as a PDF.

- Live Microphone
Put your own voice into your mix, live! You can use the Live Microphone to speak into the mix or sing to the music. Apply echo and a real-time pitch changer to your voice to sound like you've never sounded before.

- Transitions
djay 2.0 allows you to automatically and seamlessly switch from one song to the next using a variety of incredible techniques such as Backspin, Echo, Reverse, Brake, Standard, and Random.

Looping

Looping is a great addition to Cue Points that replays a particular part of a song continuously. You can create loop regions that are as short as 0.1 seconds or as long as the entire duration of an audio file.

- Incredible Audio Engine
The djay audio engine has been entirely redesigned. It is characterized by world-class sound quality and industry leading performance.
It supports more than 30 different audio formats, including all purchased songs from the iTunes Music Store. djay 2.0 will even extract the audio content from other media formats such as digital videos or QuickTime movies.

Using external audio hardware has never been any easier. Wether you are using a microphones, USB headphones, or a sound card - simply plug them into your Mac and djay will detect and perform the optimal configuration for you automatically.
