Elad,
I had (still have) the same dilemma.
Coming from Tyros 5, and beeing used of the convenience of storing everything in the hard drive there, I opted for the same way of working on Genos.
So now I have to live with the fact that I have to copy things to friends Genos internal drives, when I want my registrations to work there. Which is not always easy as the folder structures I use and the one they use sometimes(mostly) confict.
I believe the cause of this inconvenience is a technical one.
In registration files, the full paths are stored to the different aspects used (the styles, the voices, the pads, .....) when playing.
example:
In registration file C:\folder\subfolder\registration file
link to the style is stored as : C:\folder\subfolder\stylename used
link to the pad is stored as : C:\folder\subfolder\padname used
...
The problem comes from the fact that the drive letter is included in thatfull path link (in this example the C: drive). So when loading that registration file from a usb drive (say E:) Genos will look for style and pad on C: (which it will only find on that drive on your Genos and not on your friends ....)
An easy solution would probably be for Yamaha to use the drive name the registration file was started from for locating those styles, pads .... in stead of the one hardcoded in the link.
As a result, when copying everything to a usb, plugging that in a friends Genos and loading a registration file from that usb drive (which coud be named E: drive there), Genos would look for the style in the same drive the registration file was started from. So because the registration file was loaded from drive E: it would now look in E:\folder\subfolder\ (in stead of in C:\folder\subfolder\) and it would find it there.
There's been some rumours about a firmware update lately ..... who knows .....
If I remember well, things do work ok, as long as one is only using preset Genos, styles, pads. The problems only start when using aspects stored in the user area.
