Korg X5D - PC-IF drivers for NT 4.0

Have just bought a Korg X5D, but alas have no drivers to link it to my PC under Win NT 4.0. Have seen much discussion about the availabily of Win 95 drivers (which I have), but these don't work under NT. Does anyone know if Korg have released anything, or whether there are "equivalent" drivers I could use, or has anybody got the Win95 drivers to work under NT.

Cheers

Paul
