Is it possible to save PSR-640 registration memory direct to computer?

[karmapala]

Hello dear experts,

I'm new here and I hope my post is in the right category.

I have an old Yamaha PSR640 where its floppy drive already broken.
In my computer I have a very old Cakewalk Pro Audio 9.
So not long ago I bought a MIDI USB cable to connect the PSR to computer.

My question:
Is it possible to have the Cakewalk save the setting of the registration memory (4 buttons) which are in the PSR ?
(then send it back to the PSR when I need it).

Example situation:
To play a song "Waltzing Mathilda", auto accompaniment
RegMem-1 : right hand voice piano, rhythm Waltz variation A
RegMem-2 : right hand voice string, rhythm Waltz variation B
RegMem-3 : right hand voice flute, rhythm Waltz variation C
RegMem-4 : right hand voice marimba, rhythm Waltz variation D

To play a song "Mary had a little lamb", auto accompaniment
RegMem-1 : right hand voice organ, rhythm Polka variation A
RegMem-2 : right hand voice violin, rhythm March variation B
RegMem-3 : right hand voice trumpet, rhythm 8Beat variation C
RegMem-4 : right hand voice horn, rhythm 16Beat variation D

Before the floppy drive broken, I can save the registration memory for each song in a floppy disk,
then when I want to play one of the song, I just can call it back from the floppy to the keyboard
then when I play the song on the PSR, I can change the melody voice/sound by pressing one of that four buttons.

But after the floppy drive broken, I have to re-set the registration memory each time I want to play a different song.
So I wonder if it's possible to save the setting of each song as a file in the computer via Cakewalk,
where (maybe, if it's possible) I can send the data of the song's registration memory also via Cakewalk to the PSR before I play on the PSR.

(FYI, I'm trying to avoid spend money to fix the floppy drive or buy a USB emulator as the replacement of the floppy drive).

Any kind of help would be greatly appreciated.
Thank you in advanced.
