a 

Returns the current A value. 

amplitude 

Returns the current amplitude value. 

evaluate 

Evaluates the parameter using the following formula: Output = atan( ( amplitude * cos( ( param * frequency) + phase) ) ) * a and returns its value. The following condition should be verified: –263 < (param * frequency) + phase < 263.
 

frequency 

Returns the current frequency value. 

phase 

Returns the current phase value. 

setA 

Sets a new A value.
 

setAmplitude 

Sets a new amplitude value.
 

setFrequency 

Sets a new frequency value.
 

setPhase 

Sets a new phase value.
