Sure!  If you think of the patch that I described earlier with an 
oscillator driving an EG and the EG driving a VCA as one unit (I 
called it a granularizer), then I used four of these.  I played a 
mono chord on an external synth and sent that output to the input of 
each 'granularizer' (using a mult).  I sent the output of each 
granularizer to a mixer and spread the stereo field.  Here's a 
diagram:

            VCO->EG->VCA---->mixer 100% left
            |
            VCO->EG->VCA---->mixer 50% left
           /
Mono chord

            VCO->EG->VCA---->mixer 50% right

            VCO->EG->VCA---->mixer 100% right

Granular synthesis is usually done digitally so that you can get 
many simultaneous grains (the basic Kyma.5 system can get nearly 100 
simultaneous grains, for e.g.).  With analog we are limited by the 
number of modules.  Even so, you can get some very interesting 
timbres with just a few 'granularizers'.

BTW, if you input guitar into a single 'granularizer' you get very 
good tremolo!
