float outOsc = (pow5(sin(phase)*H1) + pow5(sin(phase*2)*H2) + ...// etc. additive synthesis algorithm; "H" values are the level of each harmonics.

phase += freq;//(if...)

float out = mA0*outOsc + mA1*mX1 + mA2*mX2 - mB1*mY1 - mB2*mY2;

mX2 = mX1;

mX1 = outOsc;

mY2 = mY1;

mY1 = out;

left[frame] += out;

My problem now is that the tune is always the same. The cut of frequency controls the tune but not the MIDI keyboard!!

The filter seems to work, the sound is filtered, but not tuned.

Would someone have an idea?

Note this : I did not find where to add in my project the

double FilterKernel::GetFrequencyResponse

function. I do not think that this is the problem.

Thanks...
