i used a strange mc.pfft~-based effect(involving chebyshev polynomials applied differently by order to each bin, and with first-kind-chebyshev used to alter amplitude in a certain way, while second-kind-cheby used to alter phase in a certain way..) that turns the sound of the standard-max-included 'cello-f2' sample into something more like an overwhelmingly bassy didgeridoo, for the main bassline here👇

(will share the patch some other day after i've used it to control weather systems for creation of hurricane-sized didgeridoos, but for now, hope all can tolerate the music 😇)
