Now A and C : these settings will change canopy curve (cambre)
Canopy curve is a term for how much C-shape kite has. I'm sure Regis meant curvature of airfoil (camber) like he also wrote.
By adjusting the mixer it is possible to alter airfoil shape to lower or higher camber. This can be done also in the bridle itself, but at the mixer bridle is collected together and universal adjustment is easily possible. However it sometimes may be better to adjust just certain parts of the wing.
Normal neutral "factory" setting is, or at least should be, the best setting in general. For example if all Pulsion users found out kite is better when tuned to higher camber it would mean kite has been designed with too low camber airfoil.
Mixer tweaking is always fine tuning, it is a false thought to think it is possible to change kite behavior grossly. You can't take a BladeIII kite, install a mixer in it and adjust it to a depowerable kite. It is not possible because airfoil shape is too far what it should be in depowerable kite. And as less you can take an Access and tweak it to high camber power kite. In both cases not only airfoil but every part of the kite is wrong shaped for new intended use.
Mixer itself pulls kite as it is designed, nowadays usually B is pulled 1:4 and C is pulled 1:2 of the bar movement. What then happens in a kite depends line row locations and setting itself/bar sheeting position.
Neutral setting is the only one with no distortion (or less possible). The bigger mixer tweak is the less smooth kite will be.
