Started making a DARM BLRMS monitor for violin modes

In order to more easily track and notify on rising violin modes, I've started making a DARM BLRMS monitor around 490-520Hz. This is currently in position #8 in place of Camilla 6600-6800Hz that didn't give expected results (alog73272). It looks like its working, but not the best it could be. Jenne gave me some pointers that I'll try at another time to get this to better show us the violin mode total magnitude. Once it's looking acceptable I'll make others for the harmonics as well.

Added some more notches for the other harmonics and upped the attenuation on the bandpass. I also took over slot #9 for the 1k violin modes. I think they are working somewhat well, but I'd really like to watch this next time we have a violin mode ring up to see if it's accurate.
