Neural DSP Quad Cortex 5-stars Reviews
great product
After used Fractal Axe Fx 2 and 3 for seven few years, I'm delighted with the Quad Cortex!
Perfect form factor.
As soon as you open the box and take it out you feel the quality straight away. The Quad Cortex is simply lovely to hold and looks sleek and modern. The touch screen makes it look on par with an iPhone or Android device. The fact the stomps double as knobs make this super easy to use.
This ease of use is my favourite thing about the QC. My previous modeller was always hassle for dialling in tones, particularly heavy tones, and always sounded a bit plastic. When I enquired about it on the related forum people were recommending third-party IRs. The QC, on the other hand, works great out the box with no IRs needed as the ones supplied do the job.
If there's any downsides it still needs some features like a looper and desktop app, and some more models, but like all of these types of devices its an ever evolving platform and they're sure to come.
I think overall, though, this device has been a great purchase. I've spent far less time dialling in which means more time playing and simply having fun. If you are already familiar with the plugins and love that sound then this device is highly recommended for if/when you decide to start stepping out of the bedroom.
Best modeller out there right now
I wanted to get my self a proper modeller for home studio use. Obviously the Neural QC platform is still under development and upgrades are expected, but it already shines out with super practical user interface. It is extremely easy to build setup, the capture feature is excellent. I can't compare it to others like Kemper but I managed to capture multiple pedals, amps with very close or equivalent tones. It has brought tons of inspirations for playing. I use it as a standalone or sometimes linked with my UAD Apollo, bringing analog and USB signals both in. Allows me to get some top notch recording quality plugins to the signal path end but still have option with all the amps QC platform offer. Actually you can use this as a standalone audio interface and route your signal in various ways in DAW mixing QC unit externally and plugins in computer. Absolute joyful device.
Great unit!
I've never really used modeller units before this and I am so happy with the purchase! I love the Neural plugins and use them all time and also I had to find a way to make my traveling rig more portable, this does the job very well! Fits in my backpack so handy for gigs. I haven't used it with any gigs yet, but hopefully I may put it to the test soon.
I've got nothing to complain about regarding the Quad Cortex. Easy to set up, very enjoyable UI and making presets is not only fun, but simple and straight to the point!
Neural DSP nailed this one!
Great unit. And it will be better!
I have had my QC for some 6 weeks now. As a satisfied long time Helix owner I wanted to try captures and also something smaller for live gigs. The UI is so intuitive and you know what to do very quickly. The sounds - amp sims are at least as good as Helix, the downloaded captures quality vary and it depends but most of those I had tried (JMP 1959, Bogners XTC, Mesa Roadstars...) are phenomenal and became a part of my live presets. With the time this unit will offer more and more effects. I do not regret and it is a keeper for me!
Very good device
Sounds very good, wide functionality. The only thing that fails is software support. There is no template editor, a very inconvenient mobile application.
