Since a few weeks the sustain pedal of my Yamaha N3 is giving mixed signals. I don't know any better way to describe it. I started to notice it while I didn't use this pedal, the notes I played kept delaying; as if I was half pedaling them.

When I connect the N3 to a computer, using MIDI, I can see this pedal is sending signals to my recording software, specially when I don't use this pedal at all.

I did a reset.
I checked if the cable was well-connected.
But this didn't help.

* Did anyone ever have this experience as well?
* Does anyone have suggestions what to do about it?

Thanks in advance!
Jef

That's clearly not right. Impossible to tell whether it's an electronics fault or something with the pedal mechanism/potentiometer. Either way, time to call Yamaha for service.

Thank you for your reply, Gombessa.
I just called with a Yamaha technician. Next Tuesday he'll check out my N3.
Let's wait and see (hear).

Just a small update regarding this problem.

Today, a Yamaha technician took a look at my piano.
The cause of the problem was a worn out potentiometer. It was replaced by a new one, and everything works fine again.

Glad to hear it was an easy fix!

Pots are one of the more "consumable" parts of electronics. Hopefully for high end DPs more manufacturers start moving to non-contact sensors such as optical.

Is this something that now that you have seen him replace it, if it happens next time, would you be able to just order the replacement potentiometer and replace it yourself to save a service charge?

I'm asking this for myself as well, in case the pot in my N3 pedal lyre gets worn out, too. I assume that it's inside the pedal lyre at the top itself. One time, the vibration transducer in my N3 went bad, and I was able to just call Yamaha up and order the part and replaced it myself without a service call. Luckily it's on the outside underneath the N3 so I didn't have to take the top of the N3 off to replace.

That's where it was.

He removed the pedal lyre, and it was right underneath to where it was connected to the piano.
It was pretty easy to remove the old potentiometer and replace it with a new one.
Next time I will be able to do it myself.

Thanks! Did he just know well enough to immediately replace the potentiometer right away? Or did he take some time to arrive at the conclusion that it was the pot that's gone bad? Apparently he came equipped with a new one ready to swap out.

He immediately knew what was going on, without any research.
Just a swap and he was done.
