Hi Ola.

In the TRACKS window right click on a track and select a PORT. A dialogue will open asking you to select a VSTi. Once you've loaded the VSTi, make sure you have the MIDI THROUGH checked in the OPTIONS-MIDI THROUGH menu.

Right click on the track again to select a MIDI CHANNEL and PATCH and you should then be able to play that sound. Be careful not to move off that track or the playback will stop.
