EMC style works can not convert styles to Audya series format or Midjay Pro format. The last Ketron products covered are midjay / midjay + and SD3/SD5 keyboards.
For Audya series there is software Audya stile compiler - you can download it here: https://www.ketron.it/en/software/49-utilities/audya-style-compiler-1
MidjayPro can convert all of older styles in .PAT format by itself. You have to put the folder with styles on USB stick then select MEDIA - select the USB - open folder and select one style in .Pat format. The machine will display the message: Convert style [style name] into new KST style format giving you options: All folder / selected file/ cancel. Select All folder and it is done.
