I'm trying to use a flash drive with my PX-360 for the first time. I found a stick to use (USB 2.0) and formatted it without the "quick format" option to FAT32 using Windows, just like the user manual recommends. Plugging the drive into the piano seems to have no effect whatsoever. I don't get any feedback on the screen (such as "mounting," etc.) and my flash drive does not light up as it does when used with computers. Attempting to access "MEDIA" from the main menu results in a "ERROR No Media!" message.
Here is a list of other things I've attempted to do without avail:
1) Add a "MUSICDAT" folder to the root of the drive.
2) Use two other flash drives.
3) Power off and on my piano.
4) Perform a factory reset on my piano.
5) Unplug all cables from the from the piano (headphones, sustain pedal, power) and reinsert just the power cable.
Based on my forum searches, it seems like a variant of this issue is common on the PX-5S, but the solutions there seem to do with a separate firmware issue. Has anybody encountered an issue like this on the PX-360, or else would anybody be able to offer some advice?
Thank you for reading.
