Hello,
I want to know as much there is on  piano sound characteristics. I am
trying to emulate piano or pianolike sounds in CSOUND.
Which formants are there in play?
Do they alter when you increase velocity and or playing from low to
high?
What does exactly change in the spectrum when velocity is increased?
How does the sound evolve over time when looking at the spectrum ,
attackfase release?
Sure there are more characteristics when trying to emulate ... wich?
Is there software for investigating formants?

Many thanks in advance!!
Greetings Hans van den Tillaart.
