Hello,
I want to implement keyboard tracking for the cut off frequency of a LP filter. I just can't find the maths behind...
Say I play a A4 = 440 Hz. My filter is set on FC = 1000 Hz. A certain amount of harmonics are cut, which is what I want.
But if I play A6 = 1760 hz, the fundamental is almost completely cut !
And if I play an A2 = 110 Hz, the sound keeps many harmonics and sounds too bright...
I have been struggling with maths, but I can't get any good result.
How do you implement keyboard tracking ?
