I'll bet that you are using the built-in Microsoft synth that comes with Windows. This works a little differently to most soft synths in that it is external to Cubase and the audio goes straight to your soundcard rather than through Cubase. The only way to record this is to run a cable from your computer output back to the computer input. You will need to switch off all other tracks and just record the MIDI part.

Some audio interfaces also allow you to record what you are listening to directly but exactly how you do this depends on your particular interface.

Cheers
