Yes I read your post before
I too have set up envelopes in this manner, though I don't have a midi device to correspond, I'm just using a Traktor Kontrol F1 these days.
My request was to have a visual interface just like the envelope, accessed by right clicking on any property as we do so far, but it consists of 2/4/8/16 squares that you simply click once for on and once for off.
It was just a thought as to how this could be done quickly during a show, I have preset envelopes to use but still feels like a long way to get there.
Bravo for putting the time in to get that midi setup!
