Ketron xpc should work on Windows 98 but not in Windows 2000 and XP
You can try this driver instead
http://www.yamaha.co.uk/xg/html/software/s_serial.htm Yamaha serial port midi driver
does the same job and works fine for ketron too in all windows versions
And yes necdetdoni is right you need to make shure that your default midi out in your favorite software is selected to serial out driver
and also you have to go to midi section of your Sd1 and turn your midi input for GM to PCcable
