  Applying a Langevin description of the linear sigma model we investigate four
different scenarios for the evolution of a disoriented chiral condensate:
annealing or quench with initial conditions governed by effective `light' or
physical mass pions. We present pion number distributions estimated from the
zero mode (i.e. k=0-field) component. The best DCC signal is expected for the
quench scenario with initial conditions centered around zero as would be the
case of effective light `pions' close to the phase transition. Our
investigations support the idea of looking for DCC formation in individual
events.
