HD3 + Mac Pro 5,1 = FAIL

[suicune]

Yeah I'm increasingly convinced HDX won't be the future for us either. After so many years running everything TDM tracking through plugins and not even thinking about latency having to mix and match DSP/native plugins would feel too much like a very expensive downgrade. I think it's more likely we'll end up going native and run at a very low buffer all the time. It's a shame really.

Oh well, I'm glad I at least got this system working which will keep us going as we are for a few more years yet.

Thanks everyone who tried to help!
