MIXING & EFFECTS

Fruity Formula Controller

Fruity Formula Controller is an effect plugin that processes user-defined formulae to create a controller signal. Fruity Formula Controller will appear as an internal controller option in the Link dialog. As with all internal controllers, the formula output can range from 0 to 1

Parameters

A/B/C - These knobs can be used as custom parameters in your formulas. You can access their values via the a, b and c variables (see the list of available objects and functions below).
Out - Displays the current formula value (empty bar is 0, full bar is 1). To see how the formula output develops in time, use the Meter view (see below).
Formula - Type here the formula to be used. Press ENTER key to compile to formula. If the formula is a valid math expression, you will see a message 'Compiled OK' below the formula. Otherwise, you will see an error message explaining where the mistake is.
Compile - An alternative to pressing ENTER in the formula edit box. Click here to compile the formula.
Info - Click INFO to see the formula description (by the author). The text is editable and supports rich text formatting (RFT). You can also paste RFT text from WordPad.
Meter - Click METER to see a graph displaying the formula output in time. This is a very helpful view, especially for programming LFO units.
