Hello Rak,
actually the measurement process is quite different from the Kemper: when you do a profile with the Kemper, moving the microphone a few centimeters on the cabinet or changing the microphone create everytime a new profile. It is quite easy to do 100's of profiles, this way.
With our process, there are A LOT of measurements involved for only 1 cabinet and 8 microphones (each cabinet has 8 microphones).
So basically, talking about the time it takes to do only 1 cabinet, you should compare really to A LOT of Kemper profiles.; )
About the .tur user files, we have to remember that most of our customers are pro (sound engineer, guitar/bass players, venues, backliners...) and they most of the time don't want to share, because that's their job.
This is changing now especially with the C.A.B., and we just released the Torpedo BlendIR to simplify the measurement process and IR mixing as well. So the Exchange website will hopefully disappear in the actual format to be more user friendly, what you see is a prototype (an lod one, I admit).
Increasing the community aspect of our products is one of our main objectives. For example the possibility to log in from the BlendIR to the Exchange website is something we will add in the future.
I was going to ask if any new cabs were coming anytime soon.
We have a few ones on the pipe.
