You need to control the level, duration, and slew rate (attack/decay 
rate) for each step of the envelope. Seems to me, then, that a 
multi-stage envelope could be done with a multi-row sequencer, a VCO 
clock, and a voltage-controlled slew limiter. One row controls the 
final signal level for each step, another row controls the duration, 
and a third row controls the slew rate.

Not a cheap solution, and -- unlike Grant's functionally dense Wiard 
modules -- pretty bulky.
