Newb needs help with sustain pedal for is5!

[Newb]

Hi all,

My dad gave me his keyboard - a 15-year-old is5. I bought a sustain pedal, but nothing happens when I plug it in. The manual says something enigmatic about changing to a global setting, but I don't know how to do it - something about floppy disks?! Even if I manage to get it into global setting, I don't know if it will help.

Unfortunately my dad doesn't have any of his old floppy disks! Does anybody know how I can get the sustain pedal to work? Do I need floppy disks at all? Perhaps there's a way to hook it up to my computer and find a driver for the sustain pedal? I have no idea how these things work, to be honest.

I know it's old so I can only pray that somebody has some experience with the is5!

I would be ever so grateful if anyone could give me any advice (other than buy a new keyboard.... I'm sure I will do in about a year's time).

Thank you,
Graham
