These violin modes cannot be damped without changing the dampig filters: EMTY modes 6, 12 and 20, and ITMX mode 2
For ETMY we are currently damping ETMY mode 11, and mode 18, but mode 12 is only being prevented from ringing up, and is consistantly in DARM, however the bigger issue is that the mode 12 filter crosses the mode 20 peak, so it is currently impossible to damp both modes 12 and 20, thus mode 20 has gone undamped. For ETMY modes 1 and 6, the mode 6 peak is not in the flat top of it's damping filter (though not far from the flat top), so it seems that mode 6 may have shifted down in frequency, and while mode 1 filter seems ok in foton, it's not possibe to damp both modes 1 and 6 at the same time, so both filters are a priority. Currently ITMX mode 2 peak is damped enough to not ring up, but it's filter overlaps other 504Hz peak damping filters, so without a filter change, the mode 2 peak cannot be damped. On ITMX, modes 2, 3, and 4 filters are updated to reduce their interfearance.
