Thats true, but the voice controller is generally part of the host
environment, not a plugin. It would typically be the think wihich is
resonsible for splitting the MIDI data to multiple sub-patches and routing
the CV streams (velocity, aftertouch) appropraitly. The modules within the
sub-patch can be completly ignorant of the voice allocation.
