[PD] stochastic masking of pulsar generator

[ronni montoya]

Hello, i need to mask or anulate individual grains  from an grain
generator(pulsar).
I would like to mask or anulate some grains using the masking trick
described in the book microsound.

the idea is to mask some grains  based on some probability table  ,
for example an envelope: imagine and envelope that
goes from 0 to 1,  when the envelope reader is 0  then  the
probability is 0 and it would be no masking  when is 1 it would mask
everything, and when the value from the envelops is 0.5 it would mask
by a probability of 50%

Do anybody have tried this in pd? any idea?

Thanks


R.
