This is certainly not a dramatic problem for me, but it is counter-intuitive to the way I work. And I really think I am not alone in work style.
I usually record by making a rough cut, then listening to it, then another cut of the same passage, then listen, and so forth, until it sounds correct. Especially with Comping available. The tracks stay armed.
Other times, I will record a practice session with close mic on each player, and we will listen to the recording, then Ctl X the recording and go on to the next song. Sometimes I will save it off but usually it is not a thing to keep. But the tracks stay armed even during playback.
Final mixing is an infrequent event in my world. I prefer to record more than mix/master.
So my tracks usually stay armed but at least half of the time they are in playback, not recording. The rhythm of the recording process is record, listen, record, listen, over and over. And in Sonar there is no reason to dis-arm a track to listen to it (except for the lack of metering).
In Sonar, at the end of a take, the VW meter shows the peak value of the last recording. But the second you playback the armed track the meter will show the room background noise in the mic instead of the sound of the recorded material you are actually listening to.
For me, it would be nice to get a meter on what I am hearing during playback even if the track is armed. Of course, once the recording button is pushed I need to see the VU meter of the recording, as always.
