Virtual DJ 7: Pro
This latest version keeps VirtualDJ’s famously extensive feature list still way ahead of the competition.
VirtualDJ 7 brings you all the latest technology and improvements from the DJing industry, while staying true to the core values that have made VirtualDJ so popular: accessibility, versatility and cutting-edge technology.
FEATURES
Multi-Deck
With VirtualDJ 7, you can set yourself up with 4, 6, or any number of decks up to 99.
Now it’s up to you to see how far you can go. Unleash your creativity.
But rest assured that your software won’t be the limit.
Line-in Inputs
Always wished you could run your analog device input or maybe a live musician through your software? Now you can by bringing them all together inside VirtualDJ.
With VirtualDJ 7, you can set as many input channels as your audio hardware supports and route them to any deck at will.
You get full control on the input stream, including applying effects, visualizing the beat-waveform, synchronization, beat-matching, and more.
You can also instant-record a portion of the input stream, and then replay and scratch it as you want.
Genius DJ
Be sure to keep your music library always up-to-date.
If you have a Premium Membership, you can ask GeniusDJ to recommend and download new songs based on a selection of existing songs, or based on your mixing habits.
You can also use GenuisDJ to automatically top-up your folders with the latest songs from the same genre.
No matter how you will choose to use it, keeping your library on the edge has never been so easy.
DJ Controller Support
Atomix Productions worked with all the main DJ manufacturer brands (Pioneer, Numark, Denon, Vestax, Gemini, Hercules, Stanton, American Audio, Behringer, Reloop, etc…) to ensure that most of the DJ controllers on the market today work plug-and-play with VirtualDJ 7.
VirtualDJ 7 comes with predefined mapping for most of the DJ Controllers (more than 80 in the default installer, and more can be downloaded from the website), but the mappings can be easily changed and tweaked to your liking.
