First of all, keep this in mind:
"Existing profiles and rigs will not be affected, and will keep the sound that you are familiar with."
And what about this?:
"The result is an increased authenticity, even of profiles created
previously, and an improved performance - especially when played through
a speaker system with a linear response down to the lowest frequencies,
such as a PA, or studio monitor system"
I´d love some clarity on this
