When I hold down multiple keys (3 or more), I get a rattling and ringing sound that resembles a school bell or for alarm (fast "ding ding ding" sound").

It's a recurring problem, and multiple repairs haven't fixed it yet.

Welcome to the forum! :)

Sorry to hear about the issues you've been having - you mention multiple repairs, what have you tried so far?

First a couple of questions.

1) does it occur with all voices or only with certain patches?

2) does it occur with only headphones or only speakers or with both?

3) could you possibly record the sounds and post them on soundcloud with a link to this thread?

Thanks, everybody!

Full disclosure, the keyboard is actually a band member's, and I'm posting on his behalf. I'll try and get as many details right as I can.

We've taken to a local repair tech (only guy in town) more than twice. I believe he's just been cleaning out dust, cat hair, etc under the hood and where the keys actually trigger the sounds/patches.

It occurs with most voices, and it occurs through headphones and through the main outs to PA. It only seems to be triggered when holding down 3 or more keys though. Single notes are generally unaffected.

I'll try to get a recording of the sound up soon.

Apparently he needs to keep the cat(s) from sleeping on top of the Motif, and/or to stop petting the cat(s) while playing the Motif. :) And if he doesn't have a case for the Motif, it sounds like he should get one so he can keep any dust, hair, etc. from getting inside of the Motif when it's being stored.

Actually, tell your keyboard guy to backup his settings and then perform a factory reset or Initialize procedure as outlined in his manual.

If the problem persists then it is definitely hardware.

It took a while, but here's the video showing the problem. Any ideas what could be causing this "fire alarm" type sound?

Seems to me that it's a firmware problem.

Check Yamaha's website and install or reinstall the latest firmware.

If you still get it after that then contact Yamaha support and email them the video along with a description of the problem and the steps you've taken so far to repair it.

It doesn't seem to sound like any hardware failure that I've ever heard.

Wow! If dust and hair is the cause of that, you have just alerted me to put a cover on. My keys are never covered 24/7.

Dust and hair and crud is the number one cause of failed or stuck or loud notes.

There are two tiny rubber suction cup membrane switches under each velocity sensitive key.

When you leave a keyboard uncovered dust gets sucked into these cups on the upstroke and clogs the switching mechanism so that one or both of the switches fail.

Dust is definitely NOT the cause in this case. More likely a corrupt firmware.

All the same, whenever a keyboard is not in use it SHOULD be kept either covered or else sealed in a road case.

It almost sounds like some kind of rapid arpeggio effect, except it doesn't sound like it's using the notes in the chord being played.
