• Higher than Saturation Value, the rotation speed become a constant (=Saturation value).

Frequency: input frequency multiplier: the multiplier is extrapolated within Start and Saturation values.

Volume: like Frequency, the sound volume is extrapolated within Start and Saturation values.

multiplier:
<1 : acts as a divider
=1 : use input values
