It's just that there's a *big* difference
between latching control
values when starting a note and being able to "morph" while the note
is played... I think it makes a lot of sense to allow synths to do it
either way.
Should controls have a flag that indicates whether they are continuous vs
note-on ? They can certainly be both or either one. It is a hint to allow
the host to send init-params at init time only (and a hint to the user).
Obviously the plugin has to ignore it no matter what.
