Anyone else experiencing loud digital noise bursts since the latest Nano firmware update?

Nano Cortex
1

I experienced very loud, random digital noise bursts from my Nano Cortex while playing through it yesterday. Each time it happened, the noise lasted for about 30 seconds, and didn’t stop even when switching presets on the 2 footswitches.

At one point, I shut the unit off and on again, and experienced the same noise after some time, even on a different preset. This has not happened before, and is very concerning since I use it live at my gigs. I’ve had the Nano since mid-October 2024.

I recently did the latest firmware update on the Nano about a week ago, but haven’t really used the unit until yesterday, so maybe the firmware update is the culprit? The only other thing I did was change the order of the 4 presets on the 2 footswitches, and maybe a couple eq/fx settings.
Before the update, I never experienced any of these noise issues.

My signal chain is: Guitar → Drop Pedal - > Nano Cortex → MOOER Babybomb power amp pedal - > 1x12 Mesa speaker cab. Power supply is a 1 SPOT PRO CS6.

Update: Sooo, I took the Nano to my gig last night and this noise issuer happened about 6 times, causing me to power cycle the rig, and the last time I power cycled everything, the noise came on immediately, making the Nano completely un-usable and we had to cut the last couple songs of the night.

You know the dream all musician’s have where you’re at a gig and your gear doesn’t work and you’re standing there like an idiot, but then you wake up and realize it was just a bad dream/nightmare? That was me last night, except I didn’t wake up lol. Disappointing and embarrassing, to say the least.

Is there any way to capture logs/reports etc from the Cortex cloud app or the Nano itself? I emailed and sent a post to the support team, so hopefully there’s a fix or maybe the unit needs to be exchanged. Meanwhile, I better upload my captures to the cloud…

Holly-molly, that’s not good at all, dude !

Keep us updated on the support team response, please and thank you !
I personally haven’t experienced such thing !

have you tried resetting the NC to factory settings and maybe re-install the update after that as well ?

Hi everyone!
I experienced also this weird “digital noise” today.
Never happened before.

Any news on this - or even better - any solutions in sight?

Cheers

Sorry to hear. Wonder if it’s a power supply issue? How did it happen for you?

Neural replaced the Nano for me after I wrote to them about the noise and some other issues. I didn’t experience the noise again with the replacement, but I did have issues with volume bursts and the save light coming on when I would change patches at gigs. They suggested trying a different power supply.
I ended up getting rid of the Nano. There were some good captures available, but for me personally, I was using 2 or 3 similar captures, and with the switching issue and volume bursts, gaps when switching presets, etc, it wasn’t worth the hassle.

I actually really like this little baby!
I captured my own amps with different gain stages and it sounds just gorgeous!
I’d definitely prefer some sort of solution rather than sending it back…

The noise appeared all of a sudden while switching back and forth between preset 3 and 4.

Cutting it off and on from the power source did the cure. All was fine again.

One can hear some other strange noise, like a high frequency ringing, when you touch the tip of the plugged in guitar cable. I never had this on the Quad…

Once the cable is plugged into the guitar, it’s not noticeable anymore.

Forgot to say: no matter what power supply it is connected to.

Yes, that’s almost exactly what happened with me as far as the noise. It’s just appeared and then when I would power cycle the Nano, the noise would go away.

Unfortunately, this happened at a gig one evening, and after a few times of noise/power cycling, that didn’t solve the issue anymore, and the noise would come back as soon as I turned the Nano back on. We has had to cut our last set three songs because this was basically my whole sound. Pretty embarrassing to say the least, But at least it was in the fourth set.

Also good to know that it wasn’t the power supply for you, and probably wasn’t for me either.
At the end of the day, I realized this wasn’t going to be dependable in a live situation, which was the whole reason I bought it.

There were some good sounds in it, and I was able to make a couple captures of my amps as well, but still wasn’t worth it to me, So I’ve gone back to one of those MOOER JCM900 pedals And a couple other things and it’s consistent and sounds awesome!

I hope you can get it sorted, and they probably will swap it out for you. The customer service team at Neural was very good.

Thanks for the updates as well!
