For anyone wanting to replace the SSL-ish bus compressor in the pro channel (should they jump to another DAW), Waves has the SSL G-Master Buss compressor on for 29 bucks. Sounds great. No mix knob but hey, that's what aux busses are for. ;)

Having said that, when Sonar cacks out (much like the command center just did), I'll really miss the pro channel. I recently acquired the PC4k gate and comp and really like them.
