Hello,

I bought a 4GB Sony Micro Vault Tiny USB memory device, and it is the first regular USB stick I found that does NOT work on the S900. I tried formatting in on the S900 itself - won't even format it. This stick works great on my regular computers.

Thought I'd put this note out, to save someone else the trouble of buying this particaular USB memory "stick" and having it not work in their Yamaha arranger.

Otherwise, it's a great USB mem stick - very tiny, I'll use it for my Macs and find another for my S900.

Jim

I had a problem on my S900 also.....

until I was recommended the CORSAIR Voyager TD which is the best I have ever used bar none.
