I do, but they dont need to be declicked.

I dont think thats true - surely you would want the rtamp shape to mirror
the control curve, in which case the current value should always be the
closest one.

I've always dont it by generating ramps and smoothing those - I dont know
if thats mow its usally done though.
Anyway, I think we should stop this thread - my gripe was that the
requirements included a paragraph that suggested that ramped, and unramped
control streams were inherently different, and I'm not sure thats a good
idea - I dont /really/ care how thats achieved.
Precise specification of the ramp data is a spec issue.
