[sdiy] exponential to exponential

[Czech Martin]

for fast transients, the actual shapes do not matter.

So, what you tell could only have influence in the slower decay part.
You can easily test this with a simple program like Cool Edit
and piece wise linear envelopes. 

What about envelope speak through?

Initial phase is also very important for fast attack envelopes,
but in most cases it is random, if no sync is used.

The ear-brain system sometimes works strane, i.e.
the sequence of events in time can be perceptionally unclear
or even contrary to the real measured. Different perceptual pathes
in the brain take different amounts of time to process,
at the end causality and logic is enforced by the brain a few 10ms
later.
