Quantize Pitch

A path-local pitch constraint that snaps an incoming note value to this node’s authored root and scale. Unlike a global setting it applies only along the routing it sits on, so different branches of a patch can enforce different tonalities. Use it to keep a specific voice or line in key without affecting the rest of the graph.

Notes

• Scale and root are authored on this node, so two Quantize Pitch nodes can impose different harmonic constraints in one patch.
• A connected Scale value overrides the authored Root and Scale parameters and is lowered into those params for runtime.
• When connected, Root In and Scale In override the stored root and scale parameters for explicit host or graph-driven harmony.
• Does not read patch-wide key context; connect or configure a Quantize Pitch node wherever a pitch path needs harmonic constraints.
