   I have always had the impression that you needed something similar of   
   a continuous waveform to get the FFT, trying to take the FFT of a   
   single pulse does not make a lot sense.   
      
   While the decaying part of the piano waveform could be simulated with   
   a series of sine waves multiplied with a curve simulating the   
   inversely exponentially dying out string oscillations, the attack part   
   of the waveform is far more complicated.
