VIRTUAL DJ

VIRTUAL DJ play 2 songs at a time in only one player experience disco role disk

VirtualDJ is a DJ software for PC and MAC.
It is used by DJs to replace their turntables and CD players, and use digital music instead of vinyl and CDs. 

In the same way that the CD players used by DJs have more options than a regular Hi-Fi CD player, VirtualDJ has more options than a simple media player like iTunes. It lets you "mix" your songs, by playing two or more tracks at the same time, adjust their relative speed so that their tempo will match, apply effects like loops etc, and crossfade from one side to the other. It also lets you scratch your songs, set and recall cues, and all the other regular features DJs expect to find to be able to mix.
It will let you organize your collection of tracks and group them easily in a DJ-friendly way, using filter to find the hot songs, or find compatible bpm or key, access your previous playlists, etc. And if you're missing a track, VirtualDJ will automatically find it on the Internet and stream it directly (*requires an additional subscription). And, using the millions of automatic reports we get every day from other VirtualDJ users around the world, it will give you meaningful advices on which songs other DJs consider to go well after what you just played.
VirtualDJ can play not only audio tracks, but also video or karaoke, if you connect your computer to a projector or the club's screens. 

It comes with a plethora of effects, ranging from traditional flanger, echo, etc, to more modern "beat-aware" effects like beatgrid, slicer, loop-roll. And if you mix videos, you'll also find a lot of video effects and transitions to play with. Its built-in sampler will let you spice up your mixes with a broad range of drops and loops, or you can go creative and merge live performance and production by creating remixes on-the-fly by using the sampler like a sequencer.
VirtualDJ is plug-and-play compatible with most of the DJ controllers that exist on the market. Just plug yours and you will be ready to go. And if you want to change any of the default behavior, VirtualDJ has a powerful "VDJScript" language that will let you easily tweak any functions exactly to your liking. Same for the interface. If you want to change it, our website hosts hundreds of user-made interfaces to replace the default one, or you could easily create your own.
VirtualDJ is used by tens of millions of people every day, ranging from bedroom DJs to international superstars. It is used to play live in clubs and big stadiums, at weddings, private parties, or just to train at home. And in addition to being used live, VirtualDJ can also be used to record mixtapes, podcast, or to broadcast to Internet radios.

Virtual DJ (also known as VDJ) is a range of audio/video mixing software developed by Atomix Productions Inc. for use by mobile and club DJs. The software is also exclusively repackaged for Numark, called Numark CUE.

The packages run on PC or Mac to allow computer DJs to mix music or videos, with or without an external controller. DJs can control the software with a MIDI controller or using traditional DJ hardware such as CDJs and DJ mixer with vinyl emulation software and CDs.

History

The first version appeared in July 2003. VirtualDJ is the successor of AtomixMP3, which was released for the first time in September 2000. Development for AtomixMP3 stopped as soon as VirtualDJ was released as its successor. VirtualDJ was released in 5 different versions: VirtualDJ Home Edition (formerly sold at shops, now released as free edition), VirtualDJ Broadcaster (available online and in shops), VirtualDJ Pro Full (only available online), VirtualDJ Limited Edition (free with selected MIDI controllers), and VirtualDJ Pro Basic (a budget alternative to VirtualDJ Pro without MIDI control). In May 2014 VirtualDJ 8 was released, which was completely rewritten.

Features

Starting with version 7.0,VirtualDJ supports up to 99 decks. 4-deck and 6-deck skins are included in all editions of VirtualDJ 7. VirtualDJ offers video mixing and scratching. Vinyl emulation allows the user to physically manipulate the playback of digital audio files on a computer using the turntables as an interface. This allows DJs to scratch, beatmatch, and perform other turntablism.

NetSearch is a feature introduced with VirtualDJ version 6.x. At the first few releases this allowed users to access music and videos from content providers on internet. The music and videos would be streamed directly to the user's decks, and no downloads would be allowed, except for local web cache, protected by digital rights management. From the release of VirtualDJ 6.1 in May 2010 this model was replaced by a subscription model, with Grooveshark as the content provider.

MusicGroups was a feature added to VirtualDJ 6. MusicGroup collects track histories, and publishes them on Virtualdj.com. Licensed users can make their own single-user groups, or can join a multi-user group. Each MusicGroup page includes a mini-blog, with track history, as well as top 20 played tracks, and saved tracklists. Other users can make comments to the group, and subscribe to the group. The software analyzes track lists, and makes suggestions to what track to mix next. The suggestions are based on what other DJs around the world have played next, with a stronger weight on the MusicGroup the user subscribes to. In essence a real-time track advisor based on evaluating what other DJs around the world are mixing.

VirtualDJ provides two ways for DJs to broadcast their mix sets to the internet. With the built in radioserver in the software a DJ can broadcast from his own computer by publishing a link generated by the software, that streams the mix played. The software can also broadcast to a webradio that runs Shoutcast or Icecast servers. VirtualDJ basedwebradio has been running since 2005 under the name VirtualDJ Radio.

From VirtualDJ 6, mapping to MIDI or HID controllers changed. In earlier versions mapping to a controller was done with the mappers built into the software, or by hard coded DLL files made by users (using C++ or other programming languages). VirtualDJ 6 introduced VDJScript language,^[2] making a custom mapper for any MIDI and HID controller easier by editing the mapper configuration of the software, or by editing an XML file.
