Question regarding both HDX and Carbon

[nst7]

I had been looking at the Carbon, or possibly an HDX card. I had some questions about the Carbon, but realized that possibly the same question would apply about HDX.

I have never used an HDX or TDM system, always native. I went from a 003 to a USB interface, to HD Native/Omni. I have always been fine with a buffer of 64 for recording, regardless of what interface it was.

I was hoping to find out more specifically how bad native latency is for Carbon, being AVB. I guess my main concern is for using native amp sims, and also using a native reverb on an aux track. I know they mention you just have a little naturally occuring pre-delay that way, but does that still work ok? Has anyone tried it that way? Or have you tried using a native amp sim?

The reason I also mention HDX, is I realized that some of these issues could also be the case with HDX. I've never bothered to find out how HDX handles trying to record with a native amp sim, or using a native reverb on an aux. Is that doable on HDX?

The last question is along the same lines, regarding virtual instruments. Again, is that doable on HDX or Carbon?

I guess I'm trying to find out how much of any of these issues has to do with these being DSP systems in general, vs. specifically Carbon being AVB.
