You can mostly get there with bunch of EQ instances, splits, and routing - but that workflow is slow to iterate, easy to break, and hard to make repeatable. Even when you nail it once, auditioning variations, recalling the exact blend later, or automating it musically usually turns into a technical project. Interloper collapses that whole chain into a single playable instrument, so you can move fast: try combinations in seconds, lock in a blend you can reliably come back to, and perform/automate the morph over time-staying in creative mode instead of wiring mode.
