Usare gli Stems


Cosa sono gli stems


'Stems' refers to the individual parts of a track that put together make the song, such as the vocals, the instruments, the drums, etc.
VirtualDJ 2023 uses advanced technology and the power of today's computers to instantly separate any loaded track into these basic components, in real-time. This opens the door to new ways of mixing that were simply not possible before, and will forever change the way DJs mix. Weither to perform live mashups and remixes, or enhanced seemless transitions, mixes made by DJs using VirtualDJ 2021 just sound better than what can be achieved on older software or hardware, no matter the DJ's skills.



Come usare


Con i Pads





If you just want to quickly turn individual stems on and off, you can use the PAD buttons.
Seleziona 'stems' nel menu a discesa della pagina dei pad per caricare i controlli stems

You can then use the PAD buttons either on the screen, or on your controller, to instantly remove any stem, or quickly get acapella or instrumental versions.



Con gli EQs


But in order to take full advantage of the new stems, we recommend using the equalizers

La cosa migliore è usare un mixer midi a 4 lettori
This way, you can keep the traditional frequency-based equalizers on the central channels, and use the eq knobs of the outer channels 3 & 4 to control the stem-based EQs.
But if you don't have a 4-deck midi-compatilbe mixer, there are other ways. Click on the small down-down arrow near the Vocal equalizer to see all the options.

È possibile scegliere tre modalità, a seconda del livello di DJing:

- EZRemix: Con controlli separati per la voce, gli strumenti e il beat, questa modalità ti consente di suonare immediatamente con la tua traccia ed eseguire fantastici mashup e remix al volo. Ruotando le manopole a sinistra si ridurrà lo stem nel mix, mentre girando a destra si isolerà questo stem.

- ModernEQ: This mode give more control to advanced DJs, with separation between hihats and kicks. It will feel familiar and natural if you were used to frequency-based EQs. This mode is great to perform seamless transitions, where you can control the 'energy' of your tracks, by adjusting each side's hihats, while ensuring the kicks don't interfer with each others. The middle knob will let you adjust both the vocals and melody to avoid clashes. Turning the middle knob to the full left will kill both the melody and vocals. Half-way to the left will kill only the vocals. While turning to the right will first boost a little the vocal, and all the way will kill the melody.

- Stems: Usando tutte e 5 le manopole del mixer, inclusi guadagno e filtro, puoi controllare singolarmente ciascuno dei 5 stem principali, aumentando o abbassando ogni componente.



Prestazioni





Stems separation involves some very advanced mathematics, that require some serious processing power from your computer.

Our algorithms have been carefully hand-optimized to run on any consumer-level laptop while taking full advantage of your hardware.
Se il tuo computer ha una moderna scheda grafica Nvidia o un chipset Apple Silicon, VirtualDJ eseguirà questi calcoli in tempo reale utilizzando il processore della scheda video e tutto sarà istantaneo

Altrimenti, l'analisi utilizzerà la CPU e, a seconda del tuo hardware, potrebbe non essere possibile in tempo reale.
If that's the case, you just need to prepare your tracks in advance by letting VirtualDJ save the stems in a separate file before your gigs.
And if you still need stems during a gig for a file that you didn't prepare, VirtualDJ can also run the stems separation at a much faster speed for real-time separation, but with a reduced quality.
