LFO has no effect on iOS

[MartinTremblay]

The LFO don't seem to have any effect on iOS.

This code works on desktop and android, but the oscillator is unchanged on iOS.

    let lfo;
    let osc;

    document.addEventListener("click", () =>
    {
        let options = { frequency: 1, min: 0, max: 4, amplitude: 1};
        lfo = new Tone.LFO(options).start().toDestination();
        osc = new Tone.Oscillator(440, "sine").toDestination().start();
    });
