All ,
 I recently read that Serge had a "Negative Slew" module.  
Can anyone shed some light on what this means?  I can think of a few 
definitions for Negative Sew but most of them make no sense!
thanks

Without seeing it, I would guess from the name that it is a differentiator
as opposed to an integrator. Using RC circuits, you would swap the two
components (of course that's not how we really create a lag module).

A slew module is a kind of low pass filter that resists quick changes in
voltage. It smoothes them out.

A differentiator is a type of high-pass filter that would do the opposite.
It would pass the full voltage if the input voltage were changing quickly,
but die down as it gets closer to steady state.

It would be very hard to draw what this looks like with ASCII characters.

Picture a triangle wave in. A slew/lag module would tend to integrate that
to something like a sine. A differentiator would make it look like a very
fast rise time that then falls off slowly... then as the triangle starts
it's downward slope from the peak, the output would go very quickly negative
and then gradually rise up to zero...

Ahh, it's too hard to describe.

steve,
it was the negative slope portion of what is now the "dsg" module. right 
about the time i had gotten my serge ( circa 78), they combined the 
"positive" and "negative" slews into one more powerful module.
best,
