im running under Core Audio!! Many thanks for that. I have Pro Tools M audio on my Mac with an M-audio Fast Track Pro. I wouldn't have worked it out myself. I'll have a tinker tomorrow.
Pro Tools M-Powered is not Pro Tools, it's a cut down native only version that works with regular audio interfaces. The full ProTools, powered by hardware, works under DAE. This is the mixing engine underneath Pro Tools.
You cannot use AudioSuite plugins in Logic with your version of ProTools M-Powered, as far as I'm aware (I'm not a PT user).
