Neural DSP Quad Cortex 3-stars Reviews

Random Distortion

Ive had to stop using for gigs cause it started randomlyt clipping although everything was gain staged properly. Im also reluctant to use it for gigs now even when I get it repaired incase it happens again. Or at the very least im going to need a back up rig with me at all times.

sold it

i just sold it because of the politics of the company - e.g. support, forum threads shut down and long time promised features are still not there. if they will be released you will have to pay for it - i assume but i think it will be the case - also because in the end it is all about selling the company like it has been done with dark glass. the effects are not so good. it's still a green banana.

Cheap hardware, broken promises, lots of troubleshooting time

I switched from Kemper and spent hours and hours troubleshooting this thing. Some say that the CPU inside is less powerful than what Amazon puts in their Fire TV stick sold for $25. I believe that, because despite overly promised functionality you can mostly get constraints and spend your time troubleshooting noise, hiss, kinky user interface probably built by someone without a basic design degree.

Guitar is a joy time for me, I spend big buck for this hobby. And this product just is not good enough.

Also — many say that NeuralDSP plugins sound _better_(!) and you can buy them for 49$ on sales. They promised their plugins will work on this unit — but come on when I googled what CPU was inside I'm like what.... are you kidding me.... It's 25$ on Amazon in a great product, not only a processor inside. And this is like almost $2000.... a joke.

Greed, promises, unexperienced designers.

This is basically just a prototype... (and you can't direct monitor on Windows)

Direct Monitoring feature still is unusable on Windows as of January 2022. I have tried every QC OS update/USB driver/windowsOS workaround on the PC of every bedroom producer I know and all with the same result. The entire signal gets bitcrushed when you record, fizzy unusable mush. Line-outs work just fine. Never had this issue occur on a Mac.

Side-note: I'm pretty disappointed that many teased features (such as being able to load Archetype plugins, having a desktop editor) have not been added and at this point never will be. I anticipate they'll put out a new unit with this feature in a few years and leave any early adopters in the dirt. This unit is rusting away, a waste of potential. The company's focus seems to have shifted almost entirely to their plug-in users. Not acceptable conduct at this price-point. I dare you Neural, prove me wrong in the next update

Lastly: flimsy unconditioned power supply, should come with something more reliable. USB 2.0 Type B is practically extinct why is it on this unit? Why doesn't the app have audio demos for user presets? Why is it so cluttered to navigate? Why is there so much latency switching presets?

It's still in "early access" mode

The good stuff:

- It sounds amazing

- Interface is quite intuitive

The bad stuff:

- There's still no desktop/mobile editor which should be available since day one!

- a lot of people are experiencing wi-fi issues (device must be connected to wifi to update and most of the times it fails to connect)

- a lot of users are experiencing sound issues when using it as an USB interface (the last update fixed it for me, but not for everyone)

- DSP gets filled up very quickly (but they are optimizing it and it's getting better with updates)

- limited amps/cabs/effects

It's still early in development, so you're more or less buying a promise at this point. It has great potential for which I believe it will achieve, but for now, I can hardly recommend it.
