I think I have a bad unit, going to return it. But does anyone have a NP4 they consider in good working order, where notes jump out at maximum velocity sometimes. I have had this with single notes and clusters. Really disappointed, never had any problems with the Stage range, but recently got a NP4 for a better piano playing experience at home. Surely the keybed should be able to handle any style without problem, I am playing some quite intense stuff, but I've never had any problem with my NS2

Someone posted a video recently that displayed this problem - he had good keyboard technique (which sounds like it may apply to you as well from your description). Someone with more expertise than I responded that the way the triple sensors work may be affected by dirt or other factors. You may want to talk to the shop where you bought it for an assessment - perhaps clean the sensors or even try another unit and see if the issue replicates there. Good luck!

That's me! I'm the user that posted this similar sudden spike in velocity issue. According to the USA distributor for Nord, this is due to debris in between the key sensor. I plan to take it to the shop to have this repaired under warranty. I'll keep you posted on the outcome.

Side note, I replaced the first NP4 I bought from Pro Audio Star (USA) due to the same issue, however the replacement unit had the same problem! The store wouldn't do a second exchange because they assumed I was making false claims. I spoke to the store manager and he was very rude. He said his technician couldn't replicate the issue and blew me off. For all I know, the technician probably played for a couple seconds and called it good. The store is likely resold the faulty unit as an opened-box item. I'm sorry to the buyer of this opened-box item.

Sorry that you're experiencing the same issue, but in a way I'm glad to know that I'm not the only one experiencing this issue. I'm not crazy after all.

It looks like I'm having the same sensor-velocity issue with my new NP4. While playing some quite passages a couple of keys can suddenly "pop". I can not reproduce this 100% of the time but these sensor peaks are pretty consistent across C3-F3. Not sure what to do.

Since your board is new, call your dealer or local Nord support and have it fixed. If it affects a group of adjacent keys, it's another issue than the dust discussed here. It is possible that the keys are sampled in groups, and maybe there is a loose connection in one group or area of keys related to the upper sensor. Thus, it may require a repair visit for your board.

I noticed this problem of hight peaking on a nord stage 3.

Ever get that sorted out? Both my NS2EX 88 and my NS3 88 do that. It’ll scare you right out of the moment, won’t it? I had to buy a cheaper 88 key controller bc neither Nord is studio worthy like that.

This is unfortunately well documented: (starting at around 5:30).

Not sure is the same issue as the OP -- and not sure everyone who's posted in here has which of the two.

The one in the YT video, I can confirm I have it on the NS3 88. But to be honest it only shows up when you purposedly try to trigger it, not in normal playing. Also, in my case only on black keys.

Can anyone confirm that it does not occur on the Nord Grand?

You first should be happy with your new instrument! One idea is that it has to do with the keybed - the one in the Grand is definitely different from the Stages and Pianos.
