Doesn't seem to be a typo - but rather an attempt to level the bands. However, that leveling doesn't seem to be optimal: By default, the LM band is a bit attenuated .. but when set to 0.15 like the other bands, the LM band gets too loud. By setting the following values, my frequency analyzer displays a rather flat response:
Code:
prm.drv0 = 10^((slider1 * 0.16)/20);
prm.drv1 = 10^((slider2 * 0.1)/20);
prm.drv2 = 10^((slider3 * 0.14)/20);
prm.drv3 = 10^((slider4 * 0.16)/20);
