lets see how you can do with aftertouch effects on damper return function during note-off events. :-)
We've had this conversation before - here...
They say a picture tells a thousand words...

What you are looking at is the acoustic keypress, the delay before the sensor picks up the movement, the initial calculation for NOTE ON (This is when AfterTouch starts - in red) and note duration, the gradual acoustic key release and finally when the sensor picks up key release (stops After Touch and sends out an arbitrary value for NOTE OFF)
What you get through MIDI (in green) is an approximation of what's actually happening at the acoustic keyboard... As I said before, MIDI in it's current state is not able to do what you'd like.
WHAT YOU CAN DO...
is Beg, Beg, Beg Modartt to read and recognise the full data transmitted from your strip and replicate the actual* key movement of your piano - not the MIDI conversion. Subject to copyright of 3rd Party software - they may not agree to this?
* I say actual (this is wholly dependant on the data detail of your strip).
