Yuck. Predefined... ok, I do that effectively. You get the bank you have 
set. This could be costly if you have banksize 0 (infinite) and a whole 
lot of tracks, but with a whole lot of tracks, banking just makes more 
sense. (Len reminds self some surfaces would prefer to go to bank 
starting at rather than next/last) Lots of refreshes is not nice for dumb 
surfaces where metering will be turned on manually or at surface start and 
expected to be there till shutdown or bank change. (or turned off) Blobs 
of even 8 values (more useful size) are not so easy to spread out to 
meters on a dumb surface even though they are less traffic.

All of these always on feedback types will need a timer. We can't send a 
meter value for every sample or every meter calc I think. (same with
