yes i know he has, but its more complex than that,
it looks like the crossfader from 0%-50% is assigned to the beatmasher @ 50% + > its modulating the transpose effect aswell (but inverted) and the vertical fader is modulating the gater effect but also the beatmasher (again inverted so fader @ 100% = BM effect @ 0% although it doesnt seem to drop below about 50%)
