----- I have to confess that I do not know what "velocity" means in MIDI, but
in piano playing this means the speed with which the key is depressed, and
that determines the "strength" of the note sounded. However, it is the timing
of a note and not its strength that determines what is perceived - the
precedence effect (used to be called the Haas effect) says that the first
sound to arrive will determine the timing, and if the same sound is
reproduced stronger slightly later, it is still the first that determines the
perceived timing. And fortunately, timing is what a piano roll can provide,
although it cannot provide individual dynamics. I think that it is the
precise timing that actually makes the illusion created by piano rolls so
good.
----- in stating the above I will not say that the pianist does not think
that he regulates the dynamics for each individual note - he may or he may
not - but then the pianist also thinks that the feeling with which the key is
held down _after_ the sounding will influence the sound. It will influence
the pianist only (and perhaps an audience with eyes open to watch the
antics).
Kind regards,
George
