If you are doing loads of VI work then AU is fine but RTAS would be handy for anyone trying to mix on a Logic TDM system who has less than a HD2. You run out of slots pretty quickly especially when using plugins like Echoboy which take an entire DSP. I'm on HD3 accel and I run out of DSP from time to time as well. RTAS would take the pressure off. Jim
