Disklavier

I'm pretty sure that I've seen mention of a tool that will convert MIDI files from on/off pedaling to gradual (or continuous).  Of course, it won't magically insert more pedaling expression, but it could make the transitions a little smoother.  I'm imagining something that would convert a pedal on from an instantaneous transition from 0 to 127 into a very fast transition from 0 to, say, 110 and then a slowing transition as it approaches 127.  Also, I'd like the ability to convert the minimum pedal value from 0 to something like 10 or so.

What I'm trying to avoid is the "thumping" that some songs have when the solenoid is forced to go swinging back and forth between 0 and 127 so rapidly.  Does something like this exist?

Thanks.
