Today I connected my Roland G70 keyboard and the Fantom together for the first time via a MIDI cable, and tried out some sounds, playing on the G70 into the Fantom. They sounded all very dry and without any depth, not at all like the way they sound on the G70. And almost half of them was mute.

I tried to record some sounds from the G70 onto the external sequencer board in the Fantom, together with sounds on the internal board, and it all worked fine.
But when I tried to save the project to the USB memory stick attached to the Fantom, something very strange happened. I named the project F, but when i loaded it again to check if it was saved, another project came out, a project named Fan!
Then I made another project and named it 5, but almost t he same thing happened...when I loaded it from the USB memory stick into the Fantom to check, a project called 1 was loaded instead!

I thought maybe the projects called F and 5 had been influenced or contaminated in some way by other projects with letters or digits that was already in the project names in the USB stick, so I called the next project I made E. Because there was no letter E in any of the names of the projects already saved. And now it worked! Now both the external and internal sounds were saved, and everything was ok.

What really happened here, is it something wrong with my Kingston 4 GB memory stick, or is it something peculiar happening with the Fantom?
