Setting of arrays via messages or tabwrite is not very fast in general.
Depending what you are doing, the fastest solution would probably be
to preload the waveshaping functions and interpolate between them.
Really depends ..

In general control rate processing in PDa is rather slow because it is not
integer optimized, so sending a lot of messages around will slow down
the machine. Then there are several places where the performance could be
improved.
