Could it be that your tip is uneven? An uneven tip with heavier sections or gouged areas that are thinner than the surrounding cane, will encourage cross-vibrations that use these places as fulcrums. This translates to higher "upper partials" and "chirps" (or whatever terminology is in vogue at the moment for unattractive buzzy additions to the tone you are striving for).
The tip MUST have an even, gentle gradient from the blend to the tip and should be fractionally thinner at the corners. In addition, all four quadrants should look the same - same length, same gradient, same thickness.
I suggest you try and even out your tip with an extremely sharp knife using only the weight of the blade. Try and "dust" away the tiny discrepancies by dusting from the blend to the corner of the tip, all four quadrants. This will lower the pitch and you will need to clip - it's all good, shorter tips are longer-lasting and more stable.
A really important part of this is using a sharp knife. If you are having to put pressure on the knife to remove cane, two things happen; you gouge uneven troughs into the cane, and you ALSO heavily massage the remaining fibres of the tip which weakens them and severely shortens their life.
