Nice, thanks Tim! So I've helped in a way to improve moOde?! 
BTW, removing a curve doesn't work via GUI, maybe I've damaged something or there is a bug.
And for the other question I see, max boost equals the same amount of attenuation on main level for the peak level to stay the same. Drawbacks of digital
BTW, master gain can't be adjusted precisely with the graphic slider (2.8 or 3.4dB, 3 is not possible), any way to have it the same way as other gain, by entering it?
