Thank for all of you for the tips.
I do not think I would learn MIDI (I did not even mentioned it,
because I do not know what it is :))
or Java; neither would I start constructing my electronic musical
instrument;
I use Mathematica because I am NOT interested in low level programming,
neither in hardware,
I am interested in problem solving.
Since there is no possibility to learn within Mathematica what Soundnote does,
therefore what I could only do is to get the profiles of musical
instruments from the net, (the overtones: the addends in a finite
Fourier expansion, if I understand well), and use Play to create, say,
piano sounds with arbitrary pitch.

Thank you again,

Janos
