How to read reactive state from imperative contexts (audio/music)

const tick = (currentTime: number) => {
    const measures = getMeasures(); // computation that uses stores/signals
    const time = getCurrentTime(measures); // bars, beets, 16ths e.g.: 12:4:2
    if (!measure) {
        stop(); // updates several signals and stores
    }
    else {
        setTime(time); // updates a signal
        instruments.forEach(instrument => instrument(time)); // also consume signals
    }
}
