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:
- 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.
- Enter a formula or select one from the plugin presets and make sure it compiles correctly.
- 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.
- 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.
Parameters
- A/B/C - These knobs can be used as variables in your formulas. Enter them into your formula as a, b and c variables (see the list operators and functions below).
- Formula - This is where you enter your formula. Press ENTER or Compile to compile to formula. If the formula is a valid mathematical expression, you will see a message 'Compiled ok' below the formula. If it's not, you will see a helpful error message. NOTE: The output of the formula must range between 0 to 1 in order to qualify as valid control data.
- ? - Opens the Syntax, Objects and Functions table (see below).
- Compile - Compiles the formula. Alternatively press ENTER when using the formula edit box.
- Comments - Type comments here. If text exceeds the height of the window a scroll-bar will appear on the right side. Supports RTF text from WordPad. The formula Monitor graph also displays behind the text for your convenience.
- Monitor - Shows the output from the formula in real-time. NOTE: Many formula will not display as a moving trace until you click Play on FL Studio's transport panel.
