You guys always do this!
  nothing happens on the forum ...until i leave town (and civilization)!
  so...OK! i get the message .... i can take a hint!

(i guess i'm just disappointed that my travel agent has sold out my
secret itinerary!)
...from a ranger station deep in the Olympic peninsula...

John's analysis of the implementation of an 'envelooper' is a good one
....if you assume the conventional model of an ADSR as a
foundation...but the term 'envelooper' is really just a sort of
fanciful conceptual starting point and it does not imply that the
nomenclature that has accreted around A-D-S-R is applied to the
design. With a gestural engine under the hood, the output function
need not conform to either 'segments' or start/end points that remain
fixed while the function is  in motion. i brainstormed with Grant off
and on for quite a while on what something called an 'envelooper'
would do*... and he was able to think outside my box every time!

(slaps mosquito!)

* i even built a couple of my concepts as demonstrations... but Grant
ran circles around them
