hi Gareth,
the standard midi interface, as it exists today anyway,
is unlikely to behave in the way you expect.
The Note-On is a "fast as possible" guess, and
one function of the pitch bend data is to quickly
correct guesses that were out by a semitone or 2.

That's why a midi guitar won't play right at all
if the pitch bend on the detector doesn't match 
that on the synth.

So a your rock solid instantaneous switching system 
would be messed up by unexpected semitone or tone
jumps.

Unfortunately you'll still be relying on the midi
note-on conversion for accuracy.


The kind of lookup table you described to sort out
the midi CC into the right notes would be easy to
achieve in Plogue Bidule ( in case it's not possible with
the software you're using).

Suggestion. 
It's possible to do pitch detection with Bidule, so you
could make a hybrid system where the original note
is got by your hardware switching, and the bend info
is then calculated.
