i've got high and low rate switches, both set up as per instructions, no mistakes this time

LISTEN EDIBLE

so i could also have plain bonkers wacky ooh look barn door rates on another switch??? is it just the hellevator i want turned into a barndoor? if so how do i do that on my switches? mix channel 2 into airbrake or sommit? guess i'd prefer a switch i can flick for "extra special rates"
