I'm having a very frustrating problem. I hope I can clearly explain what's happening:

I'm saving registration of the tunes I sing on my flashdrive. When I add a new registration, some of (not all) old registration seem to disapear. The title of the registration is still there but what comes up is what ever I played last.

Imagine my embarasment when I am performing and I announce something like "OK folks let's go back to the swinging days of the big bands with In The Mood" I hit the tile "In the Mood" and a slow bossa nova style comes up!

Could my flash drive be out of memory? Too many registrations in the folder? Would I get some sort of message if there was no more memory/space?

This is happening on my Tyros 2. Any ideas?
