multistage rate level env generators

[patchell]

    Although I never actually completed it...I did something like that, but it
was hybrid.  The core was analog, used an OTA to make the standard voltage
controlled RC network, it had two inputs, one to control the rate, one to
control the level it would ramp to.  And there was a window comparator to tell
when the output was settled to the level voltage.  The other half was a micro
controller.  The parameters were stored in memory.  In theory, I could have as
many stages as I wanted....but, I will never know, I abandoned the project long
ago.  I keep thinking I will get back to it sometime....maybe.
