Hi Fran
Super Floppies do not use the 34 pin Floppy drive interface, but instead use the IDE hard drive/CD Rom interface, (Hence the 40 pins) you will therefore need to connect it to the IDE Interface in your computer.
As to the Roland, I am afraid there is no chance of it working, although you could use the drive with your Media station.
Sorry to be the bearer of bad news, but as they say, that’s life.
Bill
