i don't think, it is feasible to write straight-forward objects for 
message filtering ...

pd has no notion of control rate, as supercollider or csound have ... 
messages can be used to emulate control rate signals, however there is no 
guarantee that control rate events occur monotonic, nor a way to figure 
out its sampling rate

by downsampling subpatches you can probably get close to the semantics of 
control-rate in other systems, although it might lack some expressive
