Hi Disposable,
As I said, you can copy the styles to the internal Tyros2 hard drive or (easier) to a USB stick, but NOT to the internal USER drive (because, as I said, it is very small). In addition, only a maximum of 4 folder levels are possible in the USER drive, and the number of files that can be stored is also limited.
It is important that the style files (e.g. .prs, .sst, .sty) are unzipped. Also note that there can be multiple pages in the Style Selection display (P1, P2, P3, etc.) and that folder and file names must not exceed a maximum length of 41 characters.
As a test, temporarily create an additional folder on the HD or on a USB stick and copy a few individual styles (e.g. copied preset styles) into it to try out the basic procedure.
By the way, sometimes the Tyros2 hard drive is formatted into multiple partitions. These are then displayed as HD1, HD2, HD3, HD4. Have you checked if this is the case on your Tyros2?
Best regards,
Chris
