< a href = "https://tonejs.github.io/docs/#FatOscillator" > Tone.FatOscillator< / a > creates multiple oscillators
2016-01-30 18:40:19 +00:00
and detunes them slightly from each other to thicken the sound. The < code > count< / code > parameter sets
the number of oscillators and < code > spread< / code > sets the total spread (in cents) between the oscillators.
< br > < br >

FatOscillator is also available in < a href = "https://tonejs.github.io/docs/#OmniOscillator" > Tone.OmniOscillator< / a >
2016-03-04 22:45:03 +00:00
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": < code > omniOscillator.type = "fatsawtooth"< / code > .
