I am trying to get a piano-like sound out of a dumb digital synthesizer
(the Rayna board to be exact).  Does anyone know or have pointers:

1) how the overall decay rate varies as a function of frequency, in pianos
(it's undoubtedly different for different harmonics, but this is
a 1-oscillator approximation), and what is a typical decay rate for
damped strings.

2) Should volume be scaled as a function of frequency to offset
quirks of human hearing?  It seems to me that, among notes of equal volume,
the lower-midrange ones are perceived as louder.

Mail to me if you know (or want to know) about this stuff.
