Wobble moves the pitch around, like a record player or tape machine that can’t hold a steady speed: slow Wow and fast Flutter.
Wow/Flutter The balance between the two.
Rate (Wow) The speed of the Wow, from 0.1 to 4 Hz, with its own sync button.
Rate (Flutter) The speed of the Flutter, from 6 to 20 Hz, with its own sync button.
Shape Shapes the movement (see How the modules work). Flutter follows the same shape as Wow.
Mix The balance between the dry and the wobbled sound. Lower settings give a chorus-like effect.
Stereo Offsets the Wow between left and right. With the balance at full Wow and Mix around 50%, it makes a lush chorus.
Focus Choose the frequencies that wobble, so the bass can stay steady while the mids drift for instance.
Flux Adds randomness to the Wow and Flutter.
Big Knob The amount of the Wow and Flutter.
