[Devel] callback on parameter change?

[Ricardo Wurmus]

Hi *,

is there a callback that hosts use to notify a plugin that lv2:ControlPort
parameters have been modified?

Background:
  Now that I've removed all plugin-internal handling of MIDI CCs that would
affect lv2:ControlPorts, I have no way of performing a few extra calculations
on parameter changes. Previously, I could have run a function to update the
internal parameters dependent on the new values provided at the
lv2:ControlPorts.

I would prefer to keep these calculations out of run() and only perform them
when really needed.
