Quite so, but wasn't the original question to do with the suitability as
a regular expression pedal? As a Max (or Bidule) specific solution
it looks very neat if you can afford the audio channels.

The only problem I can see with your approach is that in removing elements
of the sine frequency to stop them modulating the control signal end up 
with a delay in the control signal, but then a rough 128 step controller 
also needs filtering.
What frequency do you use?
