For example the distinction between the control output of an envelope
follower and the gain reduction output of a compressor, the follower is
inteded to drive eg. a filters cutoff, wheres the gain reduction is just
inteded to be viewed by the user as a clue as to what is going on.

'meaningful' is probably the wrong word, how about 'useful'?
The last sentance doesn't make sense, it should start "Randomising a
control"... I think.
Also, UK v's US spelling, is there a convention in the rest of the .h
