I love using Live and Sonar together, I find each complements the other very well. If you're interested in the two together, or if you use another DAW with Live, you might like this article/masterclass by Craig Anderton in this months Sound on Sound: http://www.soundonsound.com/sos/apr05/a ... arlive.htm
I subscribe to the magazine, so I can get it online. If you're unable to download it, check it out at your favorite magazine store.
