Luka,
SD1ORG.exe - this is the file that is used for the operating system of the keyboard. It is responsible for all actions and reactions that occure on the keyboard in terms of fuctions and responses.
PBANKNS (PBank with NoSound). These are files used to setup the styles to run with the original sounds of the SD1 and NOT the sounds designed for 4.0.
To get 4.0 sounds back, go to the STANDARD folder you previously created and load the 2 files associated with the extentions (*.rld and *.sty). They should be here from the previous download and copying you did.
Thanks,
AJ
