Hello Everyone. I had to cancel my gig last night because the D and G# Keys did not work. Does anyone know what the problem could be, and how it can be fixed? Any advice would be highly appreciated. Thanks in Advance.

Hi @Pianoman

First, if your keyboard is in warranty period, then you better go to an Yamaha dealer (your one from which you bought the keyboard) and ask him to replace the rubbers for those octaves where the keys does not work. (Personally, I would change them all).

If the keyboard is not anymore in warranty, then try to open it and check for the rubbers. You can also try changing from one octave to another to see if this is the problem. They could be broken, you may see them carefully.

Check them.

Greetings,
Vali

Thanks for your quick response Vallmaties.

 It's the D and G# keys in all the octaves, meaning the entire keyboard. I've tried a soft reset at least 6 times and the problem still won't go away. I wonder if a Factory reset, or removing the USB pen drive might help.

Has anyone else experienced this problem, or have any suggestions regarding removal of the USB stick or doing a hard reset?

On which video you play the Genos1 or Genos2 ?

Your question is for keys on the Genos 1 and the Genos 2 ?

I see now, all D-s and G#-s ... 
I don't think there is a bond to the USB, it make no sense.
Seems more a motherboard problem or the keyboard's board problem, maybe in soldered pins.
Did you open a ticket to Yamaha? Maybe a call is better in your situation, is quickest solution.

I'm sorry to hear that!

Hope you find the solution fast, I bet a quick call to Yamaha will help you!

Regards,
Vali

Hello Egbertus.

It is the Genos 1.
All D and G# notes across the keyboard don't work. It becomes very difficult for the accompaniment to follow. Any chord that includes those notes goes crazy. I have removed the USB underneath  out of desperation and it appears be working now,so far.

I didn't see your post before because I have been out all day trying to find a technician or a replacement Genos.

Thanks for your response. Much appreciated.

Glad to see your problem is solved .

What?! That make no sense! This is definitely a BIG bug.
Even so, you have to make some tests! Try this TEST !

Hi Vali.
Today is the fifth day that the keyboard is working perfectly. I had read on another post related to the SX 900 on this forum about a member who was having  trouble with his keyboard, so he removed the USB stick underneath and his keyboard worked after that. I don't understand the relationship either, but I'm able to work and that's good. I'll be trying out the test and let you know the result. Thanks again Vali for your help.

Regards,
Vali

hmmm.. SX900 has no USB connector underneath.
But then, what matters is, that your problem has gone

Hi @Pianoman,

The reason for such errors (which affect a specific key in all octaves) could be a loose internal ribbon cable connection (loose contact on certain pins). Since all octaves are affected, I suspect the problem is with the cables from the MKH board (key matrix high) to the EMKS board (where the key scanner IC is located). If these cable connections are OK (and the problem persists), the aforementioned key scanner IC could be defective. See this picture:



If the problem persists or occurs again, I recommend having the Genos checked by a technician who is familiar with Yamaha keyboards.

By the way, I don't think the problem has anything to do with a connected USB stick.


Best regards,
Chris

Hello everyone.
I have done the test that Valimaties recommended 3 times now, and it hasn't found any problems so far. It's been 20 days now that the Genos is working perfectly. I am baffled as to what may have caused the problem in the first place. All USB ports are working just fine, according to the test. I can't send the Genos to Yamaha in Madrid because it would take weeks before I get it back. I'm a working musician and use the Genos 5 times a week for gigs.

We did have a technician here who specialised in keyboards, but he got fed up with the high cost of living in Ibiza  and left for Malaga in the south of Spain where it is much cheaper to live.

I am already inquiring about a Genos 2 in the hope of finding a recent used B-stock one. If not,  I'll just have to get a new one. I'm hoping that my current Genos 1 will hopefully hold out for the next few weeks.

Thank you all. I very much appreciate your helpful input and suggestions.

I wonder if the Genos 2 will improve the sounds of my styles, especially the drums.

Hi @Pianoman
I've also changed my old Genos1 to the new G2, and definitely, the sound is much better. But I had some issue with some styles, because some instruments was not found, even if I used the same LSB:MSB:PC as in the G1. I had to reassign those instruments in style creator and everything was good.
More than that, registrations works well. The only issue I had was using Murray's software to convert all of my Genos1 to Genos2 banks: joystick default options will be set to NoAssign, which is definitely wrong. I tell him about the issue, he said that this is not an issue, it is a feature he must programming    In my opinion, it is an unfinished task in its soft, it is his decision if he want to share the correct way of converting registrations or make us (at least I) stopping using his soft. BTW, it is not a complain against Murray decision, it is only my thoughts about a feature that does not work, after I donate him (I know, not a lot of money) for the G2 version of RegManager. I simply cannot use it!

Best regards,
Vali

Hmm.. Vali, you're aware that the G2 can read all G1 registrations? So you don't actually need to convert from G1 to G2? You only need to convert from G2 back to G1?

Additionally, each PSR can read the previous TOTLA registrations (PSRs970 can read T5 and earlier (as well as previous pro psr's), PSRsx900 can read G1 and earlier, and sx920 can read G2 and earlier). There has always been some backwards compatibility


Overover has posted the schematic; I was only going to point out I've seen keyboards with exactly that error, and the MKH/MKL (or in this case MK76L) board was either damaged or lose; if yours is mysteriously working again, then Chris is probably correct that your connecting cable was simply lose, beause those pcb's don't repair themselves (although I did have 1 case where the fracture was so slight that it would usually connnect and sometimes not... the budget solution was to simply glue around crack around the circuitry, and it fixed it!)

In other words, *don't* bump your Genos!

Mark

Thanks Mark, yes I know there is a backward compatibility. However, the way I used registration in Genos1 was one registration for song. And I needed a conversion for Genos2 as one reg bank for song, setting registration 1 from each registration bank in Genos2 to be one registration from a reg bank in Genos1. Saying that, that means I needed the Genos2 conversion to be made in good conditions, like every function of the registration to be read as there is compatibility to earlier model. Joystick being broken when doing conversion from G1 registration to G2 makes me using the conversion from Genos1 to Genos1 reg banks and using them in Genos2 as it is.
Maybe I was exaggerating saying I cannot use it, but I said it as I wanted to use G2 format of reg banks, not an earlier version.

Regards,
Vali

Oh, I literally create a different version (after loading the old one into G2) of Reg and style for each keyboard... but then again I work in a store, where I need to be able to demo each instrument to its fullest.

Yes, when I import my G1 reg and style into G2, I then create a G2 version of that same style, and then tweak the registrations accordingly.

Your technical knowledge and write-ups are first class. Full bodied, like a good wine, and easy to savour. The explanation would have helped me several year ago with an identical problem on the Tyros 2. And as Mark has said in another post, the eventual cure was to use some glue on the circuit board but loose cabling was the culprit first time around.
