You must not make any assumptions about data across a deactive() and

i certainly don't want my first note to go through a sweep of all plugin

previous values whenever
the plugin is run for the first time. in that case, i want to have no
ramp and start cold with the control port value.
For general purpose processing (as opposed to synthesis) that doesn't
matter in practice. Certainly not if the ramp is just one period. >> can i rely on control port data being

There is the possibility of a run() pre-roll (when nframes=0) but hosts
are not *required* to do this. Sounds like you don't need it anyway
(but in general this might need sorting out at some point...)
