I find offset mode to be confusing and potentially dangerous (mainly if you forget it's on) so I leave it alone. I have no qualms with editing an automation envelope if needs be.
I agree with this...but only because there aren't enough blatant changes in Sonar to show a user he or she is in offset mode. It's VERY easy to forget you're using it which can really be a nightmare.
However, if you are focused and extremely anal about stuff like I am and you can remember to immediately change back to normal mode, it can be a really cool feature.
For example, I'm done mixing and I decide I need to do all my automation. I start with a lead vocal and make sure that each word is heard. When I get done, I find that maybe the entire track can come up +1 dB. I can no longer use my volume slider because the nodes I created for my volume will be locked in to the automation. If I moved the fader it would only move back as soon as I press play.
To raise that track 1 dB higher, I have three options.
1. Raise all the automation I just drew by 1 dB which would be tedious and a pain in the butt
2. Raise the "gain" on the track. However, because I use gain staging to make everything just right with my plugs etc, this *might* cause audible clipping. Or it just may work.....but I'd never touch my gain for the sake of adjusting automation.
3. The correct choice, press O, the volume fader turns to a + and I raise it to 1.0, press O again to get back to regular mode...and I'm done.
The same can be done when you may have automated pans that might need subtle tweaking. For example, during guitar solos, I like to pan my rhythm guitar tracks out a little wider to get them out of the way of the guitar solo. Sometimes I bring them out too wide...so going into offset mode allows me to bring them a little tighter without touching the automation nodes I've drawn in.
The key to this is to remember to press O immediately when you're done and you'll be in good shape. :)
