Czar of Midi
Since: Apr 04, 2002
Havent used Cubase in years but the problem might be you havent assigned the midi control track to send the info to the VSTi in the audio track.
The VSTi should have its own audio track assigned with the instrument available there. You need to assign this tracks input to listen to the midi tracks output. As well you will need to assign the midi tracks output to send to the VSTi you choose. You can run several at once by the way, in seperate tracks of course.
I'm not sure if this is exact for the older versions of Cubase, but it should be.
And welcome to HRC by the way.
