amplitude moduallation

Hi there, 

Can anyone explain why this code is not right for amplitude modulation
vst?
(steinberg kit)

Trem= (1- fDepth) + fDepth * (sin ((2 * PI * 10)* getSampleRate())

At a guess I'd say you probably want:

Trem = (1 - fDepth) + fDepth * (sin ((2 * PI * 10) / getSampleRate())

it's not working either.....

If you want help then you'll need to supply a little more information.

Hi, 

I have my sine modulator working by putting in the counter....

however, I'm now having problem with my sawtooth..i just can't get the
logic right.......help please......i heard loads of glitches and
distortion..


float sRate = getSampleRate();
float Trem  ;
long cycleDur, cycleDur_half; 	

cycleDur= (1/fFreq* sRate);
cycleDur_half= cycleDur/2;
    
while(--sampleFrames >= 0)
    {
       
if (counter < cycleDur-1)
    {

      counter ++;

     }
	
*out1 = *out2=  Trem * (*in1+ *in2);

Trem= (1- fDepth) + fDepth * (fFreq*10)* (counter/sRate);
		
Buffer[iWrite] = *in1 + *in2;
