multistage rate level env generators

[Grant Richter]

A case of stream of consciousness typing (perhaps puddle of consciousness 
;^)

I did not intend my comment to seem as a criticism of your design. The use
of a  microprocessor will always add capability and functionality and result
in a superior design at the cost of software complexity.

I should have left out mention of the microprocessor at all, since it was
not relevant. I apologize for the misunderstanding.
