The way you want it as an external drive NO that is not possible. The electronics in your Keyboard are not up to it.
But it is possible to change the intern floppydrive for an USB-floppy EMULATOR.
If you send me your mailaddress I will send you a zipfile with all the info and where you can buy it.
The drive is not cheap, I paid 100 US$ for it + 20 US$ for shipment by DHL but it works very well.
