Prodigy Multitrack did not simply capture sound. It multiplied intention. Eli watched the meters climb, felt the room rearrange itself around the phrase until the single line became a conversation: harmonies that his own throat had never formed, a contrapuntal bass that arrived like memory, a countermelody that braided with his phrase and then danced away. When he played it back, the recording carried the odd impression of having existed before him—like stepping into a house where someone had just stood and moved on.
