In my case it was a MIDI filter: display messages in a debugging window 
as they came in, edit the library to handle them specially, reload and 
repeat. The result was a program that could transpose multiple manuals 
and switch between transpositions depending on button presses, but where 
the message emitted by each button was very much dependant on the 
keyboard model and manufacturer.

I'm sure there's a better example.
