Thanks Florian and Kevin for the responses, it makes a little more sense to 
me now.  I've been sick a couple of days so I'm just catching up with this and 
I'll give it a try tonight.  I don't have an inverter but I'm going to try to trigger an 
EG instead to give an acoustic instrument a new envelope so I'll just use the 
inverted out of the EG.  As I mentioned before I'm trying to experiment with the 
concept behind the Transient Designer which is supposed to be a fun piece of 
gear.

Regarding the vocoder, I find it's also quite useful as an alternate filter even 
when you don't want full-blown talking robot effects.  For example, patching 
an oscillating vcf into the speech input lets you create filter sweeps that have 
some of the character of the vcf but are subtly different as you can hear the 
bands of the vocoder.
