I'm running Cubase SX3. I'm using the internal monitoring but I don't think it's working correctly. What I want is to be able to listen to the audio on a track and to listen to what's coming in on the input at the same time. There is the monitor button there and when I use it, I can no longer hear what's already on the track. Is that normal? If so, how can I go about achieving that without addition hardware?
