I've been damping violin modes, and the ndscopes for each mode on an optic are very helpful, and since I need to watch more than one mode.  I've updated the ndscope files for:

1. ITMX mode 13, first attachment, I added the gain to the top plot, which also has the output
2. ITMX mode 17, second attachment, I added the gain to the top plot, which also has the output
3. ETMY mode 12, third attachent, I added the gain to the top plot, which also has the output, and I added a third plot, which has ETMY modes 18 and 20.
   • my observation about mode 18  is that it suffers little to no ill efects by damping mode12
   • my observation about mode 20  is that rings up as mode12 is damped, however, the increase in RMS is slow, and typically small
