Randomizer is aimed at being a simple curve manipulation tool. It is meant to be used with the curve editor and to have terminology relating to graphs.

Curve Types

  • random
  • noise
  • sine
  • triangle
  • square
  • bounce
  • sawtooth
  • sawtooth (parabolic)
  • sawtooth (parabolic reversed)
  • sawtooth (exponential)
  • blip
  • sine blip

Parameters

Amplitude: Scales the curve in the Y axis. You can set the pivot of the scale point to either center, min, or max, depending on how you want your curve to scale.

Frequency: Scales the curve in the X axis, and pivot frame serves as the pivot point for the X axis scale, so if you set to frame 1050 and scale the frequency, frame 1050 will remain the same value and scale outward from there. Position X and Position Y: Simple controls to move the curve up and down and left and right on the curve editor.

Advanced Usage

You can sort of 'stack' or drive multiple curves by expression linking another curve/randomizer into the Position Y, amplitude, or frequency knobs, or by manually animating them. You can achieve some pretty dynamic results. Squarify option: Makes random and noise steppy, and includes a random seed button.

This tool can also be used with the Wave Machine toolset.
