You are explaining NOTHING in the video. 100 % realistic, 100 % realisti, 100 % realistic... yeah, we get that now But again, you are explaining really nothing... very weird?!
But please answer the simple questions (I have already asked above):
1. In your first comparison video, did you use the Kemper direct profile and converted IR or is it direct profile into an IR loader with the original IR?
2. How can you guarantee 100 % realistic sound, when using CONVERTED IR (using cab maker)? The converted profiles will NOT sound 100 % the same to the original IR you are praising - I think you know that?! That makes your whole concept questionable.
So you are basically make "special" direct amp amp profiles and then just copy your already existing IR in - after you converted them with cab maker, which makes the cab part sound and feel different compared to the original IR (in my experience).
And your secret method is only a benefit, if I want to change cabs in the same profile ("amp / cab separation") or maybe use direct profiles, right? Compared to common studio profiles (where no "separation" is needed) there is no advantage. Because other vendors simply profile the full signal chain for EVERY cab / mic combination and therefore I don't need to change cabs.
