Nord User Forum

I am Japanese and I am making this statement in deepL.
I am using a nord electro 4 which I bought used 3 years ago. I have not used it for a long time, but in February I started using it again.
Since yesterday, when I select program 1 and play the piano, the reverb has become stronger on its own. (To be more specific, on the reverb panel, only the STAGE light is on, but suddenly it sounds as if both the STAGE and HALL lights are on.
Even if I press the up or down button to switch to another sound, the reverb gets stronger on its own.
There seems to be no connection between the reverb getting stronger and which keyboard key is being pressed.
When the reverb gets stronger, a dot appears next to the program number, which appears when the program is edited.
I don't know why, but I recently changed the MIDI channel settings to use the electro 4 as a MIDI keyboard for the first time. Also, I have only recently started reading the manual to learn the functions of the electro 4, so the operations I have done there may have something to do with it.
Can you give me some tips on how to solve the problem?

Postscript.
I pressed the program 1 button while holding down the shift key and the memory protect was off at that time.
I have now turned it on and will check to see if this eliminates the reverb.

There was no change in the ramp before or after the reverb became stronger. Also, when I turned off the reverb that was originally set, the reverb no longer applied on its own.

Hi and welcome to NUF

Based on what you report, if you see the program modification sign then it means a parameter has changed, so maybe the problem is the knob of Reverb Depth which has become defective and needs cleaning or replacement.

As a test, try to rotate it fast back and forth for a few times then leave it at 0 position, then switch Programs (to load the program's value) and see if the problem still happens or reverb is now stable.

Thanks for the reply.
I forgot to write something important, sorry.
I had applied a delay of 10 (WET) to the original program I was using. When I set it to that setting, I was experimenting with the delay function. I am not sure if the delay and reverb knobs are linked, but I am posting this information as well just in case. The reverb was not applied that strongly to the original sound itself. (The reverberation was normal but only natural.)
After receiving your reply, I rotated the knob a few times and then set it to 0. I went back to the original program from another program and this time the reverb light was switched to a different place than it was initially.
The dots indicating the program editing concentration are still visible as well.
It doesn't sound like the reverb is being applied strongly, but I am concerned that the reverb and delay settings have been changed. I have program protection set to...
If it seems difficult to address, I will put up with this glitch.
I will try to post an image of the changes in the reverb panel before and after touching the knobs.

Sorry, I just checked the "before" image and the delay light is not lit.
I was playing with the delay on for a long time. But maybe I thought it was too noisy and turned it off somewhere.
I am sorry that I have tinkered with the settings so much by myself.
