noise elements to the sound.  Later I used the shapers to give the same 
effect.  I would try the design in the original format before modification.
As for the sound of this shaper, when the triangle wave is used you can 
get some great Farfisa-like sounds.  I originally  had a saw to triangle 
converter on the module(since my ARP 2600 only had one triangle out) and 
I put the trimmers to this on the front panel also.  When I adjusted the 
wave converter as well as the shaper I had great control.
