You could use a table mapping key-velocity to amplitude, and have
different tables for each partial, or a coupl eof tables and
interpolate......

or if you have a formula for how you want ampltidue as a funmction of
key-velocity and partial....

Not sure why I am answering as I have not used additve symth much.

You could use a bank of oscillators, each one representing a single
partial. Then simply measure the velocity and test whether it's high
or not, if it is you can use some kind of goto statement to set the
amplitudes of the partials. Perhaps there is an easier way? This is
only the first thing I thought of..
