Now I'm confused. Are we still talking about the "AM pitchshifter"
plugin (1433) ? It has a control input port called "Pitch shift" which
determins the amount of shift, you can connect any control rate signal
to that port. Or you could downsample an audio rate signal and connect
that. For realtime modulation it would probably be better to have an
audio rate input port for the shift amount though.
