MIXING & EFFECTS

Fruity Formula Controller

Fruity Formula Controller generates automation control data based on user-defined formulae. The Formula Controller will appear as an Formula ctrl - Out option in the Link dialog. It is just one of the many internal automation controllers available in FL Studio.

How to use:

  1. Load Fruity Formula Controller in a Mixer FX Slot. NOTE: Renaming the Formula Controller will help you find the correct automation source when more than one is used in a project.
  2. Enter a formula or select one from the plugin presets and make sure it compiles correctly.
  3. Link the target Synth, Effect or FL Studio interface control to the 'Formula ctrl - Out' option (or custom name used at step 1) from the Link Dialog > 'Link assignment' menu.
  4. Link other internal or external hardware controllers to variables A, B and C OR record A, B, C tweaks in real-time as the project is playing.

/ division  a/b
^ power a^b
Functions
Abs absolute Abs(a)
ArcCos anticosine ArcCos(a)
ArcSin antisine ArcSin(a)
ArcTg antitangent ArcTg(a)
ATan2 arctangent angle/quadrant of a given number Atan2(a,b)
