Replace independent Tone.Clock per sequencer/pianoroll with a single shared master clock running at 960 Hz in audioEngine. Architecture: - Master clock starts/stops with audio engine (startAudio/stopAudio) - Widgets subscribe via subscribeTick(id, callback) receiving (audioTime, elapsed) on every tick - Each widget derives its own step/position from elapsed time and its own BPM, so different BPMs stay perfectly in sync - BPM/steps/bars changes are read from refs (no clock restart needed) Benefits: - All timing derived from one clock source = zero relative drift - No clock recreation on param changes = no glitches - 960 Hz tick rate ≈ 1ms precision (plenty for musical timing) - Sequencer at 80 BPM and 160 BPM maintain perfect 1:2 ratio forever Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
