Velibor,

After taking a closer look at your question, I realize you will NOT need to reload the contents of the FOLDER.
The style GUAJIRA which was imported from the X-series is programmed such that you can play Arranger A and B (like the other styles), however, for Arranger C and D, they are already pre-programmed with Chord progressions (2-bars each). This effect allows you to solo over the instrument while the Sd1 'plays' for you.

If this is what you were refering to, the same should hold true no matter what OS you use.

Thanks,

AJ
