Scott,
You are not completely correct here. You can reload a song and a style within the registration memory section of the PSR2000. If you write a user style and save it in either user style or floppy disk, and you have recorded a song or loaded in a standard midi file and save it in either user of in floppy disk and now you make a registration memory and check all the boxes for what you want to save, you can call up the song and the style when you recall one registration memory. This way one button finds all your stored data.
