Hello to the originator of this thread.
I completely understand what you intend by the term "good midi" of Clair de Lune: you are seeking a midi capture of a live performance of the work, with pedaling and other performance nuances intact. Step-entered midi sequences or midi files that have been converted from step-entered notation programs ... simply lack that "human touch" only a live performer can give to a piece.
Please be aware that, even though a good performer can render a great live performance that happens to be captured by midi, one cannot simply "graft" one midi performance onto just any other sample library or even Pianoteq. Why not? That's because a good performer interacts with his or her instrument in real time, depending on the condition and quality of the instrument.
So, just to take a "good midi" performance of Clair de Lune and play it back through Pianoteq, WILL render a performance that is better than a step-entered file, but will fall short of sounding correctly on Pianoteq.
Enough of my rambling.
