Create a TimeClass from a time string or number. The time is computed against the global Tone.Context. To use a specific context, use TimeClass
const time = Tone.Time("4n").toSeconds();
console.log(time);
const note = Tone.Time(1).toNotation();
console.log(note);
const freq = Tone.Time(0.5).toFrequency();
console.log(freq);
