How about the amplitude? By definition an auto* will only do something if
the amplitude is changing (as if it were being played on a guitar). I
don't know if auto*'s are usually put before or after the compressor
(sustain pedal).

You need a crossfade (aka 2:1 CV mixer) module, I don't know if theres one
in SSM off-hand. I could knock one up in LADSPA in a few moments, shout if
you want one.

The LFO controls the relative levels of sig's 1 and 2 that are mixed into
the output.
This is a 1D version of vector synthesis that was popular a few years back.
