That would be five filters, One for each note with a range of one. If you 
have control of the filtering program/plugin/script (and if it is LUA it 
sounds as if you do) then instead of using > and < to set a range, use a 
lookup table instead. You only have 127 notes, so set up a table of 128 
bits and if bit[note] then apply processing. (probably not LUA style I've 
shown but the concept works) It is ok to use 128 words if that is 
easier/faster/all that is available.

Initialization would includ resetting all bits/words to 0/false and then 
setting notes to filter to 1/true.

The only purpose for this I can see is for processing drums or other 
one off sound effects.
