Public Member Functions
	Quartic (mono_float offset)

virtual Processor *	clone () const override
	Clones this Processor for polyphonic expansion. Must be overridden by subclasses.

Public Member Functions inherited from vital::Operator
	Operator (int num_inputs, int num_outputs, bool control_rate=false)
	Constructs an Operator with a specified number of inputs/outputs and control-rate setting.

force_inline bool	hasEnoughInputs ()
	Checks if this Operator has at least one connected input.

void	setEnabled ()
	Updates this operator’s enabled state based on connected inputs and external status.
