#96 ADDsynth filter keyboard tracking ignores voice octave shift

[unfa]

I don't know if this should be on by default, but I'd expect it to be.

For example I want to make a patch with uses ADDsynth's voices to create a fundamental and harmonics of a tone. But I fisrst make some weid FM modulated noises, then use a bandpass filter to filter musical tones out of that.

Tuning a harmonic series this way has do be done by ear, because the filter keyboard tracking ignores the detune/key/octave shift in the voice.

I'd expect the filter tracking then to follow the the oscillator pitch - could there be a way to make filter keyboard tracking respond to the pitch modifications done to the oscillator?
