I have had ALL the Tyros models but never has one crashed
I have had this Genos 9 months and it has crashed 5 times
By crashing I mean
a) spinning saying checking
b) Freezing unable to play the keyboard
c) not selecting the correct item ( mainly registration from playlist)
Your problem in a) is that you have a folder with lots of files in it. This causes searches to take an inordinate amount of time. You need to take your USB stick to a computer, and check each folder for the number of files in it. It doesn't matter what type they are, it's the number that's the issue. Ensure each folder has fewer than 400 files.
In addition to any USB sticks, you need to check the User drive. Connect to a computer using a standard printer cable, power on while holding down the Playlist button. Now the User drive will appear as an external drive to the computer, and you can perform the same checks.
Once you've cleaned up your drives, power the keyboard on, and let it sit for an hour. This will allow it to build the indexes it uses to speed up searches.
Cheers,
Fred
PS. None of your Tyros models had a search feature. That's why you're having this problem solely on the Genos.
