Scale and offset a parameter

Parameters

ID	Range	Default	Description
Value	0.00 - 1.00	0.00	The input value (supposed to be modulated)
Multiply	-1.00 - 1.00	1.00	The multiplication factor that is applied to the input
Add	-1.00 - 1.00	0.00	The constant offset that is applied to the multiplied input value

The pma node (stands for P arameter M ultiply A dd) is one of the most versatile tools in the scriptnode environment and allows you to scale and offset any modulation value. It's used for controlling modulation intensity, combining multiple input parameters to control a single target etc.

Be aware that there's also a unscaled version which allows you to add an unscaled offset to the value (the multiplication parameter is still scaled).
