Basically this library tries to imitate the final sound of a Hammond organ, but without recreating a tonewheel simulation. All the sound of the different harmonics is based on a sinusoidal wave.
Then an array is filled with the sum of the harmonics according to the drawbars configuration.
The sum of all this fills another array; This last variable is multiplied according to the desired musical notes.
It simulates a spring reverb (or tries to), a vibrato scanner and a pretty fun Leslie speaker simulator.
