The Robot Butterfly (formerly known as Octopus) is a digital multi-FX unit powered by the FV-1 effect processor. It uses a rotary switch to allow the user to select between eight independent patches. The controls for the effects are simply labelled as CTRL1, CTRL2, and CTRL3 as the parameter they affect will be different depending on the patch.
