Welcome Meng, and welcome back Noel.
If the months and years ahead are half as good as your introduction letter, I suspect we'll be very good friends indeed. Those of us who have stuck with and fallen in love with Sonar over the years have recently had a very sobering realisation as to what is on offer elsewhere, and frankly, it is bleak compared to what this DAW and this vibrant community has become. It was always forward thinking and pioneering - and now it seems even more vision and drive will be added to it.
I am personally really, really looking forward to NOT worrying about other DAWs for a long long time. Phew! :O)
