row sets pitch, neighbour count sets velocity. The grid runs Conway's rules and evolves
every Evolve steps, so the pattern rewrites itself as it plays.

Conway's Game of Life as a step sequencer. Living cells become notes; the grid evolves as it plays. MIDI out needs Web MIDI over HTTPS or localhost. The built-in preview synth works anywhere.
