Hi Toril,
Congratulations on your new toy
Christmas has come a little early in Norway!
Regarding the User drive on the T5, it is very small (only around 6.7 MB), but is actually the largest of all the Tyros models! It is about half the size of the User drive on the S970.
I try to use the User drive on my Tyros4 (which is even smaller at 6 MB) just as a temporary 'work space' for creating or modifying styles etc. and use the hard disk for permanent storage. At least that is the intention, but being lazy I do leave stuff on the User drive for longer than intended and occasionally have to 'clear it out'!
When you save files from within Style Creator, Song Creator etc., the selection screen will open at the User drive, but you should be able to tab to the HDD or USB (if one is connected) and save there instead.
If you want to get a clearer picture of what files are saved in the User drive, I suggest that you download Yamaha's 'Musicsoft Downloader' program for PC (link:
https://uk.yamaha.com/en/support/updates/msd_win_kbd.html ).
If you connect the T5 to your computer by USB, this program will show you the contents of the User drive in a similar way to Windows Explorer with files on your computer. This will not 'filter' the listed files in the same way that the selection screens on the T5 do, so you can see everything at once. You can use the program to manage the files if you want to, although you can't see the T5's internal hard drive with the program so you can't move files to the HDD with it. However even if you would rather do the actual file management on the T5 itself, it is still very useful to be able to see the 'full picture' regarding the state of the User drive.
Does your T5 have any expansion memory fitted? Unlike the S970 there is none built in by default. You will need some if you want to use any expansion packs or create your own custom expansion voices using YEM.
Have fun (and don't forget to walk the dogs)!
Regards
Ian
