Hay guys

I'm using Cubase SX3 and Addictive drums VST, however there is no sound coming from the Vst

Any solutions?

Thanks in advance (Y)
Make sure that the correct output is selected. This can be found somewhere in the options/preferences. Then, make sure the track has the correct output selected as well. Don't have any other audio programs running besides Cubase. I'm not 100% sure on any specifics since I don't own Cubase. You may find more/better help in the official Cubase forum.
What MIDI input are you using (keyboard, drum machine?). Make sure the signal monitoring is on, as well as the track is armed. I use Reaper, and if those things are unchecked, there's no sound either. Provide more details on your set up.
