Init()

void daisy::Parameter::Init	(	AnalogControl	input,
		float	min,
		float	max,
		Curve	curve
	)

initialize a parameter using an hid_ctrl object.

Parameters

input	- object containing the direct link to a hardware control source.
min	- bottom of range. (when input is 0.0)
max	- top of range (when input is 1.0)
curve	- the scaling curve for the input->output transformation.

Process()

float daisy::Parameter::Process

(

)

processes the input signal, this should be called at the samplerate of the hid_ctrl passed in.

Returns

a float with the specified transformation applied.

Value()

float daisy::Parameter::Value ( )

inline

Returns

the current value from the parameter without processing another sample. this is useful if you need to use the value multiple times, and don't store

the output of process in a local variable.
