Quarter tones

[J43fura]

Tone.js seems to support Quarter tones as seen in tone.js~NoteUnits.ts and tone.js~Frequency.ts

Even in Tonejs/midi as seen in:

Midi/src/Note.ts

Line 33 in 1d3a1f5

const regexp = /^([a-g]{1}(?:b|#|x|bb)?)(-?[0-9]+)/i;

However this is pitchToMidi not midiToPitch,

I am wondering if its possible to convert to Quarter tones as well, any ideas?
