Well some IRs are not in phase with each other f.ex. early OwnHammer IRs with new OwnHammer IRs... but I know there's an update coming.
I want to want this product but I'm not sure what I'd do with it. I need graphs to judge IRs so I'd have to use the old tools in addition to make it work for me.
Would be coooool if it was an IR loader and everything worked in real time. You simply disable your cabs on the Axe-Fx or have the option to send pink noise through the program. Then have it working like the "control room" in Guitar Rig 5. I think everyone with a DAW (f.ex. me) is doing this already. :S
not really possible at this time because of the way the Axe-fx II handles the cabs and how the grid works. They have to be loaded. If they did get that working like that it would be uber cool because it wouldn't have to be limited to cabs at that point, you could conceivably plug any outboard effect in realtime in a any grid location over USB. The other alternative would be to have it have its own audio engine or be a VST but I don't think that is where they want to go with this.
