Notes randomly hitting peak velocity

[ziozeus]

I got some private messages from another user who solved with a mix of all the things we are saying here. Pencil rubber eraser plus swapping seems to be the better action. I'm glad you suceeded. Well done!

Perhaps you can try to open up the unit and clean the velocity sensor and rubber contact with a little alcohol. Sometime dust, moist (in my case, it was coffee) can obstruct the sensor and create the unpredictable volume.

unfortunately this also occurs on two notes in my Grand 88

I was thinking about getting either a Nord Piano, Nord Stage, or Nord Grand, but I was trying out a Piano yesterday at Guitar Center and noticed this happening a lot. Then I went online and found that this is a problem with all three models. Really disappointing that this is a recurring issue in keyboards in this price range. I love my Electro, but I think I’m going to look elsewhere for something with piano action. No way I’m shelling out that kind of money only to have to deal with disassembling it and cleaning it within a few months of purchase.

I can only speak for the Nord Stage 3 88, but this issue has been solve with a recent firmware upgrade. I haven't had it happen not even once since.

I don't think that this issue is more likely to happen on nord then in other brands. It is simply something that can happen in modern keyboard for a numbers of reasons. Buy the keyboard you want and feel lucky, you'll probably be so.

That’s good to hear, thanks!

Ok, I think I just f*cked up my Grand. Tried to clean the sensors according to the instructions above, but I didn't use a eraser but I used cleaning alchohol and also contact spray. Now most keys don't have any velocity registered and hardly give sound. If they give sound it's only one velocity. Did I do something wrong by cleaning the carbon sensors with alcohol and contact spray?

[Mr_-G-]

I think they should be cleaned with isopropyl alcohol. Not contact spray!!

[ziozeus]

Contact spray was a bad idea.nobody ever suggested that enywhere.
I would try isopropyl now to go back, but let the chemical do his work, don't press too much, don't be harsh on the black carbon schemes, move in one direction just like you had to remove some invisible pour. Also now you will need to clean the contacts below the rubbers. Good luck!
