Below is a short video demonstration which you can pause to see the setup, but in essence for recording audio, you need to put VCV on
A) an Audio Track as an insert (you can still record live MIDI, or route MIDI from a midi track to VCV)
B) an instrument track (like you did) and record the midi, after that you use the Bounce in place feature to convert the instrument to audio
or C) set the output of your instrument track to a bus and use an aux track to record the audio.
Don’t hesitate to follow up if you have more questions!
