Parameters

For this plugin, we will define a few new parameters, including phase shift and gain.

namespace Steinberg {
	
	enum SinSynthParameters {
		kPhaseShift = 100,
		kGain = 101,
	}
	
}

public:
	float mGain = 0.5f; //needed for parameters
	float mPhaseShift = 0.f;
	
	float mFrequency = 0.f; //needed for sine wave generation
	float mPhase = 0.f; 

After this remember the steps from chapter one to serialize not only in the controller but also the processor.

Processing

Vst::Sample32* outL;
Vst::Sample32* outR;

for (int i = 0; i < data.numSamples; i++) {
	outL[i] = sin((i * mFrequency) + mPhase);
	outL[i] *= 1 + (9 * mGain);
	
	outR[i] = sin((i * mFrequency) + mPhase + mPhaseShift);
	outR[i] *= 1 + (9 * mGain);
	
}
