Detailed Description

RandEnvelope envelope class -- makes random control signals using a single line segment

Public Member Functions

void	setWalk (bool walk)
	Accessors.
void	setAmplitude (float amplitude)
void	setFrequency (float frequency)
void	setStep (float step)
void	setOffset (float offset)
bool	isActive ()
	This answers whether I'm active (ptr < end).
void	reset ()
