Zedd

At 0:12, it can be seen that Zedd is using Cubase 6.

He also mentions version 7 in this Tweet:

@steve_duda dudaaaa. LFO tool is crashing with the new cubase 7 and I'm crying over here :'(

In this screenshot from Snapchat, Zedd can be seen using Cubase Pro.

Cubase can also be seen on his computer screen in this video, In the Studio Pt. 2 ft Zedd | One Strange Rock.

Zedd claims Sylenth is one of his favorite plugins. "I ... mainly use Sylenth1. I love this plugin above everything else and can work extremely well with it." He goes on to say "I mostly use Sylenth1 – even for some percussion. I am its greatest fan!" via Beatport News

In one of his livestreams on Twitch, Zedd, in addition to play Valorant and give his feedback on fans songs, mentioned his favorite plugins, among them, Serum.

You can see a compilation of the highlights of his livestream in "Sol State" YouTube channel, in the video named "ZEDD: MUSIC PRODUCTION FEEDBACK & TIPS(& Why You Shouldn't be Avicii) [Twitch]". Serum is mentioned at 10:35 in the video: https://youtu.be/fqHvrBY-UiU

In Zedd's words (said during the livestream that can be found during the video of "Sol State" YouTube channel):

"Serum, you can get any sound down with Serum" "Serum is an incredible plugin if you want a VST that literally can get you any sound possible, you can even make drums with Serum"

Another one of the software synths Zedd speaks about using occasionally.

"I use Pro Tools for recording vocals." at 15:38.

One of the synths occasionally used by Zedd, second to his all time favorite, Sylenth.

Zedd has classical training and plays the piano, so it's important to him to use a very solid, reliable, and high-end keyboard. In photos of Zedd in the studio he can be spotted working with an M-Audio Axiom 61 keyboard controller.

While Zedd seems to be having some fun with his chair, we spotted the awesome Apogee Duet 2 USB Audio Interface in his studio setup.

Zedd can be seen wearing these headphones at 0:27

Mentioned by Zedd in this November 2017 Sound on Sound interview. The accompanying interface can be seen in this photo from the same interview.

“I don’t even have a vocal booth in my studio, because if I want to record vocals, I tend to go to Westlake Studios, which is just 10 minutes away from me, and that works well. I don’t do the engineering myself, which allows me to focus on producing a vocal, and arranging it and making sure the singer sings well. If I want to record some demo or backing vocals at my studio I use the Slate Digital Virtual Microphone System. But you know, it all works. The same with the soundcard. It’s not one of those things where I go around telling people one thing is a million times better than another. Just find a soundcard that works and that does not have a lot of latency, which is the main thing. For a long time I simply used the internal soundcard of my laptop!”

Zedd can be spotted using these Beats By Dre headphones in photos during a studio session.

"Synthmaster gives me instant inspiration and creativity. The sound engine behind the synth is brilliant and the presets offer me excellent options to start my productions. The modulation and sound design capabilities are endless and I can easily shape any sound into something that works perfectly."

One of Zedd's essential pieces of travel gear is his iPad, as stated in this May 29, 2012 Magnetic Magazine interview.

WHAT ITEMS DO YOU ALWAYS TAKE WITH YOU ON THE ROAD?

iPad, laptops, PS Vita, 3 pairs of headphones, LOTS of clothes (because I'm lazy and don't do laundry a lot), my NI S4 (DJ equipment) and Nike fuel band!

YOU’RE ON THE ROAD A LOT, ANY TALES OF EXTREME EXCITEMENT OR EXTREME BOREDOM YOU’D LIKE TO SHARE?

I either watch Entourage (and this will not last forever unfortunately), play games on my iPad or PS Vita or sleep! At least in the planes there's not much more I can do. I've stepped up my road-set up a little bit so now I need power to produce music which means that I mostly can't work in planes.

Zedd is listed as an artist who uses the Sausage Fattener on Dada Life's website.

" I also love Tone2’s Gladiator, Lennar Digital’s Sylenth, and Native Instruments’ Damage, the latter for more cinematic sounds."

Zedd's live setup consists of the S4 DJ along with his MacBook Pro.

Zedd says in a tweet reply to Morgan Page, Steve Angello, Dirty South and Skrillex that he owns the Focal SM9 monitors.

“I always have a few plug-ins on my mastering bus in Cubase,” says Zedd, “one of them being LVC-Audio’s ClipShifter. I feel that limiters cut your transients far too much, and especially in my music it’s not necessary to limit too much. So I use ClipShifter, which handles transients that go over zero better than your DAW. It can handle anything from 6-12 dB over zero. The signal then goes into the iZotope’s Ozone, in which I use a preset that gives me all the highs I need, with stereo widening. It also adds a bit of compression and maximising. At the very end I’ll then add a limiter, like the AOM Invisible Limiter or the FabFilter Pro-L, just for a little more volume."

This MIDI controller is seen behind Zedd in this picture from Rukes at Interscope Studios. http://photo.rukes.com/zeddstudio/slides/zeddstudio%20011.html It is also mentioned in a Tweet, given as the source here.

In the user-uploaded photo, Zedd is shown using Traktor DJ software, highlighting his preference for Traktor products.

"Zen Tour's preamps are extremely clean and transparent which is great for any source." - Zedd

Pause around 1:34 and you can see zedd's screen and it says kontakt in the working sample.

He says: "I love Mixed In Key for its simplicity and functionality. I always use it before I add a new song to my set to make sure I know which key it is in".

Zedd is the creator of the DOUBLE ZERO headphones, which he just launched as of 4/21/2017

Zed tweets "My dawgs from @PioneerDJ just sent me these babies!!! Ahhh amazing!!" - lucky guy!

Zedd tweeted a photo of what looks like the case of these very nice Beats headphones.
