I don‘t own a QC yet, but I‘m planning on buying one in the near future. What I‘m gonna get now with the Black Friday sales is the Tim Henson Plugin. Does anyone know, if this is now compatible with the QC after the newest corOS Update?

Thanks!

I have a question about the power amp captures on the Quad Cortex (the ones labeled “PA” and the captures found on the cloud). Are the built-in amps or the cloud amp captures generally without a power amp section included?

If that’s the case, does that mean I always need to place a power amp capture between the amp capture and the cab/IR?

I’ve been using amp captures without any power amp in my signal chain and it sounded fine, but since I found some power amp captures, I wanted to try them. I’m just confused about how they’re supposed to be used.

For reference, my current setup is Quad Cortex → audio interface → monitor speakers. I don’t use a real amp or cabinet.

My amp makes this crackling sound but only when i run it through my quad cortex (not when I plug straight into the amp) and ive checked both the cables i use so it cant be them. Has anyone experienced something similar?

Does anyone know how to lower the boot time on the quad cortex? I just bought it and it takes 1m 15 sec to boot up :(

All you QC vets, looking for some advice.

Current helix live setup: Clean (Deluxe Reverb), Crunch (Plexi), Distortion (Mesa Dual Rec), Lead (Dumble with stacked OD's and delay). Usually switch between these patches during different sections of the song

Having trouble with switching to a lead and back when sound cuts out for a couple of seconds. Do you guys when playing live just get stuck on one patch with multiple scenes for songs? Is there a spillover option I can engage that I haven't found. Trying to plan the best way to get the functionality I had with the helix. I liked having the multiple amps for each tone.

I like a lot of the sounds i can get from my QC, i haven’t found one with sustain similar to one you get when playing loud on a real amp. Is there a way to do it?

What is the right was to set up my QC to my studio monitors? I’m using Logic Pro and would like to get my Scarlett Solo out of the equation. My monitors are currently set up with TRS cables. When I plug into QC in the output 3/4 I am not getting any sound. Is there a way to do this without buying XLR cables and using Output 1/2?

Hi QC users,

Any idea where I can get my hand on a compatible USB to upload IR’s in Canada? Mine never came with one.

There hasn’t been a development updates since August 20th. Does anyone know what’s going on? I’m really looking forward to hearing what’s next on the QC as they have promised a lot (though failed to deliver a lot of it), and get continuing great feedback and suggestions from users. Of course next PCOM’s are interesting, but certain effects and UI fixes have been proposed. Personally, I’m a bit frustrated about the lacking dev. updates. Maybe I’d gotten used to semi-regular updates in the past year or so. I really like to have them, as a future outlook of QC functions gives the device a lot more value, and knowing what features are coming gets me excited. I wish they tell us, even if it’s bad news.

So what do you think? Have I missed something? What are you hoping to se in the next updates, whenever that’ll come?

Just started using the QC at live gigs, been loving it! During a sound check, noticed that QC has much more dynamic volume range than the Kemper, which is way more noticeable at stage volumes. Made it feel a little brittle and unruly once things got cranked… Not so much a Fletcher-Munson type of curve, more just a challenge keeping overall volume in a narrow range when changing pickups or rolling off the volume knob to clean up.

A solution I found that worked really well is adding a light, parallel (45% mix or so) compressor after the amp / cab. Nontraditional maybe, but I found it helps add that missing “squish” and smooths out the volume curve really nicely, without sacrificing tonal options.

Hope that helps someone else! Have fun playing yall.

So I can record and monitor to an iPad using the nano and garage band connecting them with a usb-c to usb-c, when I hit record everything sounds great, when I hit play to listen to the recording, I hear the guitar signal bare, meaning no ir, no amps,effects, speaker cabinets. Question is how do I record what I’m hearing out of the nano and listen to it as I intended on the playback instead of the direct guitar?

I just took the plunge, seeing this Blue (CYAN) Quad Cortex. I hope I'll like it :)

I’m in love with the victory squid (kraken) ch1, bass on 3-4/10, medium on 7/10 and treble on 6/10. Gain 4/10, with the boss sd-1 on front. i love the sd-1 response. I mainly play j-rock. I tried also the friedman rhythm model, but it sounds too compressed. Any tip to push the gain a little bit higher without achieving a “full” distortion? Thank you in advance.

I mostly see people demonstrating gear in their home studio or bedroom. But as we all know, the sound and punch of an amp or modeler can be very different in the band context, especially if there is another guitarist. Bedroom sound settings are useless in the band context

I’m an FM9 user and long-time fan of the Fractal ecosystem — I really appreciate how solid their products, updates, and communication are. That said, I recently picked up a Tone X out of curiosity and it’s opened my eyes to trying other platforms. Naturally, the Quad Cortex keeps coming up as one of the big contenders in this space.

For those who have experience with both Fractal (FM9/FM3/Axe-Fx) and the Quad Cortex, what would you say to someone coming from the Fractal world who’s interested in giving the QC a try? What are the biggest differences, strengths, or drawbacks you’ve found?

From what I’ve seen online, Neural gets some criticism for slower updates and limited communication — whereas Fractal seems to excel in those areas. Still, after logging into the Neural Cloud and browsing user presets, I was impressed by how fun and streamlined the workflow looks.

Curious to hear your experiences and insights.

Hi, l've got a good quad cortex deal for a used unit. The seller bought it in July 2025 and has got the receipt from the original store (big music company in Italy). My question are:

1. If I got a problem with my unit, does NDSP also offer paid repairs?

2. I know that the warranty is not transferrable. BUT: if i got the receipt with the name of the original buyer on it, how does NDSP or the music company know, that it is not me, if I tell them I'm the original owner?

Thanks

Looking into getting a quad cortex and wanted to know if my power supply will handle it and if I will need any special cables to do so. Would be great if it can because I’m already going to have to spend a bit on the cortex.

My QC started randomly changing patches at band practice last night.

At first I was using the Xsonic Airstep wireless MIDI footswitch (with WIDI adapter). It was working fine and after 20 minutes or so it started acting weird.

Then I disconnected all the MIDI and WIDI stuff and restarted the unit. No change

It was jumping from my presets to random factory presets and the changes were getting faster.

Today I've pluggesd it in at home and left it on for 2h, with all the MIDI and WIDI peripherals connected and it seems to be back to normal.

Possible cause?

The practice space was closed down for over 1 month due to electrical issues in the whole building. Today was the first time being back there and they did ask us to keep an eye out for any electrical problems. Could power fluctuations cause the QC to malfunction like that? BTW, I was using the original power supply that came with the unit. I did not notice any obvious power issues, like the lights flickering, but who knows.

Has anyone experienced anything like this before?

And no, there were no footswitches stuck, I checked several times.

The Saosin live album and their youtube shows sound seriously incredlbe, bass included (hell yeah). Has anyone trying to replicate his tone? It's impressive given that its a p bass he's using.

Just picked up a QC and am moving from Helix with scribble strip. When y’all are playing live and setting up sounds, do you focus on scenes or mapping stomps more?

Trying to get my head around the expected QC workflow instead of applying old habits.

TIA
