Hi guys,
I have my favourite NS compact classic many years. But I have very seriouse problem with lowest keys (from F1 to B1) which has been started couple days ago. These keys sometime do not work for piano, synth and external sounds. The organ sound work properly anytime.
I have completely reinstalled OS (I have 5.06 version now) and used factory sound set. Problem is time to time again. These keys some time work properly, sometime not.

It is very likely some mechanical problem with contacts associated to these 7 keys.

Do you have any experience or tip how to fix this problem?

Thanks a lot

Discussed many times here, repair requires technical skills to properly disassemble the keybed (and the reassemble) and the use of isopropyl (or other appropriate substance) to clean the contacs, just search for similar posts and you will find details.

Read for example nord-electro-forum-f9/electro-4-sw-key-only-functions-when-playing-organ-section-t13320.html or nord-electro-forum-f9/g3-key-sounds-louder-than-the-rest-nelec-3-t7802.html

Thanks for tip. I searched the Nord Stage forum only.
I just have finished gig with my NS and everything was OK. Two hours I was playing mainly pianos with standard gig instrument vibration on top of Ultimate Delta stand without any problems. I do not understand why one day is not work and day after is everything OK.
