A few 1 kHz violins rang up tonight, pretty similar to the problems described here
Anamaria set the gains to zero in the guardian for ETMY mode 18, 20, 12 and ITMX mode 13 and 19. It seems like some of these modes were turned back on since last week, but we aren't ready to have them coming on automatically yet.
She found that ETMY mode 18 + 20 can be damped using the filter for mode 18, -60 degrees of phase and a gain of -100, last week I used 0 degrees phase, which also seemed to work for both modes.
For ITMX mode 13 we have been using pitch to damp mode 13 and yaw to damp mode 19. Last week I made the mode 13 filter narrower to avoid ringing up mode 19, but didn't change mode 19. Tonight I made the mode 19 filter narrower, and changed the damping to pitch. It seems like we should be able to damp these with one filter since they are using the same setting, I tried this but it rang up both modes, so I left it as the two narrow filters.

We ran into a problem when I had commented out a mode and then once I hit load on the violin guardian, it went red. Strangely I had commented out an ITMX mode and it was complaining about an ETMY mode, but we never figured that out.
The way the guardian is written, it gets its mode info in the main, not in the run. So the state has to be rerun to get the new mode numbers.
The settings (gain, FMs, etc) however are reread in the run state, so it's ok to change those and hit load.
The solution is to set the guardian to manual, rerun the current state (so main updates its mode numbers) and then set it back to auto.
