Cubase 5 synth setup

Hello guys,
I have Arturia MICROBRUTE synth,how can I play it on Cubase?
I tried to add it as external insturment.
It just defined by cubase for the modulation and pitch wheels.

A guy from Arturia told me to open audio track and thus I’d be able to record the synth.
It worked,the problem is that if the synth is shut down I can’t hear the sound from the track I recorded.

Any help?

Thanks a bunch
