In your stated case ..... no
Fractal have made it very clear that these are not "made" / "designed" for live use -
unless you will want or prefer the sound of a baked-in room in your IR playing into a real room with its own different real room reflections ie: IR with room reflections played into a real room with with its own totally different real room reflections (!) As I've said before, would you ever [live] mic up a FRFR Cab that was already playing back an IR with the mic baked in [ as they all are ] (?)
For I.E on stage Monitoring I
can see a use whilst feeding your normal IR sound to FOH.
For home recording and bedroom-level and headphone playing I
can also see a use.
And as a
very general principle "more options" always give you "more options"
All the best,
Ben
