Tone.FatOscillator creates multiple oscillators and detunes them slightly from each other to thicken the sound. The count parameter sets the number of oscillators and spread sets the total spread (in cents) between the oscillators.

FatOscillator is also available in Tone.OmniOscillator by prefixing another type with "fat", then use the count and spread to control the number and detune of the oscillators. To create a "supersaw": omniOscillator.type = "fatsawtooth".
