First of all, make sure that you select the desired VSTi as the MIDI out on your MIDI track. If you want to export the entire MIDI event on that track, you can simply select the event and then hit Ctrl + r and the Export Audio Mixdown Window will appear. Be sure to select the folder where you want the file to wind up, and carefully choose the output that corresponds to your virtual instrument, along with import to Pool and Track, press start and your track will be turned into an audio track in your project.
