Edge Detector

Edge Detector converts zero-to-nonzero changes into single-sample Rising triggers and nonzero-to-zero changes into Falling triggers. Any nonzero value is high, including negative values and values below 0.5; moving between two nonzero values is not an edge. Connect a gate to create distinct start and end events. Edge history survives live graph edits and transport start, stop, or seek. Explicit reset or patch initialization starts low, so an initially high input produces one Rising trigger.
