PSR 640 vs PSR S670

[Ishan]

Hi !
There is a built in function to make our own styles (Drum patterns / Fill in Patterns) in PSR 640. Also can make midi tracks (midi songs ) and that can be save it into a floppy disc. Is it can be done all that operations by using PSR S670. Thank you.

Hi,

As I can see here, https://images-eu.ssl-images-amazon.com/images/I/A1eoHXswAiS.pdf  PSR S670 also have the features you mentioned.
The floppy drive was replaced by the USB
