The envelope functions in ssm are a little prone to clicking and popping, and
you have to learn how they work a little to minimise this. It's a good idea to
avoid attack times of 0 as that certainly causes an instant change - which
will cause filters and the like down the stream to pop.

In other cases it's a good idea to put a smooth stage in after the envelope to
remove these instant changes (the smooth plugin is really just a weighted
average filter).

I've recently tried building this in to envelopes directly (in some other
software), which is a little faster as you can do a check to see if it's
needed before applying it. I'll add this to the envelopes in ssm at some point.
