Len, it sounds like your method will still record midi, or will it also record audio? I read one suggestion where the VST track output was routed to a bus track, then that bus track output was routed to the input of a new audio track. However, in Cubase Artist there seems no option to route a bus output to the input of an audio track. Maybe that needs the Pro version.

If you open a vsti, F11, it will ask if you would like to create a midi track, choose yes. The device menu, vst connections is where you set up the busses. Those busses depend on your soundcard, how many ins and outs. If you open a vsti, F11, the default output buss, is probably going to be the stereo out buss, you will see the audio signal on the track fader and the stereo out buss. You still need to draw in a midi with the pencil tool for the track before you can record a midi, or you can import a midi track in, and you will hear the audio through the stereo buss, if that is the way you have the buss set up in the device menu, vst connections. Now note that if all your tracks are routed through the stereo buss, you have to mute the tracks you want silenced if you only want to render 1 track for example, M for mute button, S for solo button.
Your interface or sound card determines how many physical busses you can have, I am limited to stereo in and out, because I have an M-Audio Audiophile 2496 card, but only use the s/pdif digital in/out connected to an RME Adi-2.
I've mentioned the physical busses, you will use a physical buss if say you need to send and return a signal to a physical stand alone reverb unit, however, if your reverb is a vst, you can open an fx track, Project menu > create fx track, and choose a reverb vst. To select the send buss for a track, click on the "e button" in the inspector panel, the one on the left hand side.

Under the send column, you will click on the black space and choose your reverb. Also you have to click the blue button to activate it. Then there's a line you move to the right to send more signal.
"there seems no option to route a bus output to the input of an audio track" do you mean a group channel?

What specific bus output would you be trying to connect to the input of an audio track? Generally you would render the track and check the preference box to have it open as a new audio in your project.

see where it says mono in and stereo out in the inspector panel. this is where you choose the in/out buss.
if you click on the mono in, whatever input busses you have setup in the device setup vst connections, input busses, is what will show up here. Where it shows stereo out, will be the output busses you have set up.
