'I know that they are in "memory", not "custom".'
They are not custom styles now therefore although they may have been at one time.
If there are Custom Styles you wish to save to floppy disk and take to your computer the process is as follows...
Program Menus - Composer - Custom style copy - get 'direction' right - select the custom style by name you want to transfer on the L/H side of the screen - select Memory bank 'A' on R/H side of screen - click OK - select the memory load button in the rhythm group - save to floppy disk and waltz across the room to your computer and load from floppy using Windows Explorer into somewhere on your hard drive where you can subsequently locate it...
Now, given that you own a copy of EMC Styleworks Universal you are in a position to convert that Technics style file to a Roland STL style file.
EMC Styleworks costs around 500 dollars to buy from Klaus Grosser. Very nice man!
