Otherwise, it will basically ignore that the port was disconnected,
and keep ramping forever.
The alternative would be to require that disconnect() resets the
control automatically, but that falls in the same domain as loading
control default values, which IMO is something that the host should
do. (Explained earlier.)
Sounds logical, but one could say that the ramping events break the
rule anyway, since the ramping isn't stopped automatically at the aim
point. The aim point is just a different way of expressing slope, and
it's used only to keep rounding errors from building up. What a ramp
event *really* says is this:
"Start ramping from the current value so that
<target> is hit in <length> sample frames."
It doesn't say that the aim point is where the ramp stops. It's more
similar to just changing the ramp value directly.
Either way, it's just a performance hack, and I'm not sure it's of
much use. I've already said myself that you shouldn't do long ramps,
because they may not be as linear as you think, due to plugin
optimizations.
So, yes better stick to the rule.

Yeah. (If we
have splines, that is. Otherwise, just RAMP to the
default value, and then stop ramping with a SET before
disconnecting.)
Why do you need to stop ramping? Set the value to 0, and ramp for
1 block or 1/2 block or whatever Right.
That's why you basically don't let ramps run across block
boundaries.
That said, it's perfectly legal to aim for longer distances,
since
given that we know nothing about the future, I say no. We've set a
rule that "things happen now and in this block only". Let's stick
to it.
