Once Full Res is out in the wild, it won't be long before all and sundry (myself included) start A/B-ing Full Res IRs to Ultra Res plus Reverb (adjusted with reflections, diffusion, highpass, lowpass, etc. to emulate the Full Res).
I wonder if I will find myself still gravitating to standard IRs along with a subtle touch (often 5-7%) of the near infinite adjustability of reverb to emulate a variety of spaces, rather than the more specific baked in space that includes adjustable distant mic balance. With reverb, the diffusion & reflections etc. can all be adjusted and printed in post and as glue with the rest of the tracks on a dedicated bus. Its seems that when using Full Res it may be desireable to instantiate that same Full Res IR (or just the distant mics) on an aux bus, for using a touch in mixdown with other tracks: so they are convincingly in the same space as the guitar cabinet. Not a criticism: Just my provisional assessment that Full Res is a sophisticated tool that might be a challenge to use effectively for those with a plug and play outlook.
As an analogous note, I've made invaluable use of UAD's Ocean Ways Room Modeling Plug In (In mixdown, obviously) , so I can see real potential in Fractal's extension of IR capability with spacial modeling: And impressively: being able to pull this off in real time. I look forward to jumping in.
