Thank you for this forum and for your support. In short: The Yamaha PSR SX900 Style search is broken completely unusable, perhaps due to the appearance of many thousands (including old, but TYROS 3-working) style files in the fall of 2022.
Nothing helped. It didn't help to make facotory settings, nor anything else. After a 2 month warranty battle, I got a new Yamaha PSR SX900.
I had paid a 5-year additional 5% warranty at an additional cost. Otherwise, my Yamaha SX 900 would have been left second broken and unsold worthless. Just think how important Style Search is, because there are no more Ballad and Waltz departments, but they have been mixed up with other genres.
This same danger still exists with the PSR SX900 because Yamaha hasn't done anything about it.
On this forum, I found in the fall of 2022 that the same thing had happened to the other two.
I tried then to post here, but this forum's spam blocking was so strong that I couldn't get here to the forum to write, with my own domain mail address ending in the Swedish standard domain: .nu. Sweden's other top domain official .nu counted as spam! Sweden's official own top domains are .se and .nu
But now then I came up with the idea of signing up here with a Gmail address, so I can get this thing for the benefit of many SX 900 owners.
Other than that, I'm happy with the SX 900 and I still have a fully functional TYROS 3 from 2008 as well as a PSR SX 910 arranger. I've done myself a volume, tempo, parameter pedal for the SX900 or a cheap "FC7" pedal modification that was successful. I think write it later here.
I use it as a tempo pedal. For example, in Hebrew songs, the tempo changes, which belongs to the style. The tempo pedal doesn't get YTyros3, but the volume and sostenuto etc.
Here's a closer look at what happened and what was done. In these images, you will see faulty, strange Style file names or parts thereof that tell you about a messed up USB memory cache that could not possibly be reset. Yamaha service also couldn't get it reset, or couldn't get the instrument repaired, and they had to give a new instrument.
This clutter in memory prevents the style search function from being used. There will be no decent search results!This is a document about an underlying SX 900 bug that I understand hasn't been fixed yet with firmware updates! So be careful with your SX900! My newest Arranger is the PSR SX900, purchased in the fall of 2020. But after 2 years I noticed that Style Search no longer works.
The reason was that I had put all the possible Style files on the PSR SX900 and its USB cache memory got messed up. I tried 5 times to reset factory settings and it didn't help. Fortunately, I had paid the SX900 an additional 5-year warranty, about 5% of the additional price. Swedish

I took the device to warranty service, and after the first month they tried to claim that there was nothing wrong with the device! Although style files cannot be retrieved.
Then I complained to the dealership and demanded that they repair the SX900 or replace it with a new one. Two months passed the time, without any compensation but I got a new PSR SX900. It still carries the same risk of breakage.
So far I've put Genos styles in there and just a little bit more. But my all style files with many thousands and including old Style files, indeed broke the PSR SX900 style search function completely unusable!!!
This danger is still Yamaha has not fixed the bug with a new firmware on duty!
From this forum I got help and also proof to the seller shop that this can happen.
Thanks to you and here's the same document, and the information that Yamaha has not fixed this issue.
The same Firmware v 1.11 is still the latest with which this Style Search function breakdown has occurred.
I already have a long Yamaha Arranger history and I also still work with the TYROS 3 as well as the PSR S 910.
If anyone has any further information about this, that specifically what then is it the Yamaha Style file type that completely violates the Yamaha PSR SX900 style Search functionality then please comment here?
It may be that many thousands of Style files, exported via USB, were too many, and it seems that the USB cache memory got messed up and the factory settings reset did not reset it. Also, it doesn't help to disconnect the USB. It doesn't help that the SX900 is allowed to stay on for an extended period of time!
I'll attach here two photos of how Yamaha's memory and display got messy and broken!
In them, the USB memory is disconnected. Just the instrument is stuck! But you can play in that space, by the way.
I had spent many evenings trying to solve the problem myself, but it didn't help. Yamaha's big manufacturer's arranger broke, i.e. because of Yamaha's own style files being put in and used.
As I said still has this danger. The firmware version is still 1.11 the latest on which this happened, and no newer one has come out yet?
As an electronics designer and serviceman, I also have access to the Yamaha maintenance menu and rewriting the firmware there didn't help either, and neither did anything else. From this firmware re-flash burning warnings that it can be a dangerous thing. Well, it didn't turn out that way, though. Don't give it a try.
Now when I look at myself these photos again that I have left is it possible that this Rock1 style from the collection SD1to2k may be the cause of the failure? (ROCK1 shows a picture with a bug on top).
In first pictures in begin you see style name text "ROCK1". In this picture you see it from my computer. PSR SX900 Specs is only GE style files, which is SFF2.It is at least a good idea to avoid these old SFF1 style files. Although apparently, they too should work, that not beak the instrument!
This file has come to me from some musician friend who bought some style collection online some years ago for a few dozen USD$.
SFF GE – (Style File Format Guitar Edition, called also SFF2) is a newer format, with support for styles that use the Mega Voice, has a larger number of parameters for the guitar parts.
So this is possible that SFF1 like Yamaha 2000 style files break the PSR SX900 Style search function, but for sure can't this be said?
But this has all happened and is true. Fortunately, I paid an additional warranty 5 Years for 5% of PSR SX900 price ca. 2000 EUR, and then got a new PSR SX900.
Happy Easter!
Yamaha arranger regards
