'slow gear' effect

["Qua Veda" <qua@oregon.com>]

Is there s/w that does a good job creating a 'slow gear' effect?
Not sure if this is a common term, but the so called slow gear effect that
I'm referring to can be produced by a patch on the Boss SE-70, and perhaps
other processors.  It is a slow-attack, chorus-verb type effect that 
creates
kind of a volume swell and sustained sound.
