The XF does not show you when a File was created. You must mean when you look at the file on your computer it shows a date that is fairly meaningless. That’s probably true because the Motif XF does not have the kind of clock that’s aware of the date and time. When you turn it off it is not ‘sleeping’, it is truly OFF, and completely unaware of the passage of time. Why your computer reads that date, I really have no idea.
You may want to use the Folder/Tree function to identify your data... you can create a Folders in which you save files... name the Folder to include the Day and Time, if you need that.
Funny story, Yamaha made an FM Synth module that set the date and time (way back in the late 1980’s, it must have been too soon.. it was universally disliked (I never understood why). Any way, I have often heard this request to document, not only when, but where and even to what client a particular set of data was presented. I have recommend the Folder System, and backing up to the Cubase MediaBay/Sound Browser which lets you create a filing system to meet the most demanding needs.
You don’t particularly mention what you are filing, All data files, individual Voices, Mixing setups... if it’s Voices and/or Mixing setups the Cubase Sound Browser is worth exploring as it lets you not only capture, organize, rank, date and otherwise categorize your own data... your way.
Thanks Phil. My apologies for not being clear. I do not need to see the dates on MOTIF though. I want to see the file on my laptop. All the files created by MOTIF have this date attribute which is a bummer. I wanted to sort some of my VOICEs and see which one is the newest one (a typical task in PC) but unfortunately they all have the same date
