X50 & Sibelius v4 sound setup problems

[Jim_L]

I'm new to computer/music/midi stuff but have USB'd my X50 into my computer and can input notes to the staves in Sibelius but the program cannot play or see the sounds from the X50. My only intent with all this is to create sheet music of my original tunes that have keyboards on them. I'm musically illiterate so I figured this would as easy as plug & play...

Both the Korg & Sibelius sites (and accompanying synth & program help files/manual) are no help. I've been to other forums with no help either. Can someone please tell me why the synth sounds are not being played?

My computer sees the synth, Sibelius sees it in it's device/input manager (but has no sound set for it, tho' it has other Korg synth sound sets), Notes appear on the staves when I play the synth but no sound. I'm looking to create orchestrated scores and need the various 'realistic' sounds I used in my recordings from the synth.

p.s. I don't use computers to record music and this is a perfect example of why...;>)

I don't use Sibelius, but I have lots of other software, all of them needs the MIDI options to be set properly, both input and output must be set to the MIDI devices you use, in this case the X50.
If it doesn't show up in the list of available devices, you either have to reinstall the driver or check with the software manufacturer if the device is supported.

The device isn't supported.
