Oscillators
Oscillators are generators that produce value according to a wave shape. Common shapes include sine, sawtooth (or ramp), square and triangle.
The frequency of an oscillator in hertz (Hz) determines how many cycles of the wave happen in one second.
Warnings
Oscillators are normalised to generate values in the range of 0 to 1.
Each wave has its own character, and when coupled with other simple math operations it can get interesting fast.
