Hi John,
I strongly recommend only plugging in one USB stick at a time, especially when working with Registrations. If you connect three USB sticks one after the other, they will be recognized as follows:
- First stick: USB1 (Drive Letter in Registrations "I:/")
- Second stick: USB2 (Drive Letter "J:/")
- Third stick: USB3 (Drive Letter "K:/")
If two or three sticks are connected at the same time (e.g. when starting the keyboard with the USB Hub connected or when plugging in the Hub during operation if several sticks are already connected), it is purely RANDOM which USB number or which Drive Letter each stick gets. As a result, there is a high risk that Registrations in which external files are linked (e.g. styles on one of the USB sticks) will no longer work (because the style cannot be found due to the currently changed drive letter of the USB stick in question).
Of course you can copy all files from these three USB sticks to one stick. I recommend doing this on the computer. It is important that you have/create a meaningful folder structure for your files on the stick, e.g. main folders such as "Styles", "Registrations", "Multi Pads", "MIDI Songs", "Audio Songs", "User Voices", etc., and subfolders as needed. You should only save files directly in the root directory of the USB stick, i.e. outside the folders, in exceptional cases.
If you copy files directly on the keyboard, you have to be in the "correct" File Selection display in order to see files of a certain type. If you (on the keyboard) want to copy an entire folder that contains different file types, you would have to copy this folder several times, i.e. separately in each File Selection display. So it's best to copy everything on the computer and, as mentioned, each time use a main folder per file type on the USB stick.
Hope this helps!
Best regards,
Chris
