In the past I have always converted (rendered?) an Instrument Track (with a VST) to audio by routing it out to my audio interface (RME Fireface), then looping it back in and recording the incoming signal on an audio track. However, a friend tells me that such a method is complex and creates an addition D/A conversion. He suggests that I simply freeze the Instrument Track which automatically creates the audio track.
Is he right? What is the best method of rendering an Instrument track to audio?
