Watch. Listen. Adjust.
You never have to count the squares.
Travelling pulses and the Pulse Clock show which voice arrives early or late. The answer becomes something you can see and hear.



One move, two consequences
Build real counterpoint.
Bridges couple two voices. Gates care about direction. Beat rings change arrival time. A single turn can fix one phrase and unset another.
