Doepfer

Seems like my message didn't make it into my last message.  What I 
meant to say was this:

Of course there is no copyright.  I would be very happy if someone 
else could use this patch, or better yet, improve it. 

When using this patch, you have to tweak the level of the fixed 
control voltage and the attenuation of the random voltage to get the 
desired effect:  A certain percentage of the sampled random voltages 
will be above or below the switching point of the voltage controlled 
switch.  Then, this percentage can be varied with a control voltage.

An interesting variation is to lose the sample and hold and just 
feed the raw random voltage into the mixer.   Then, you will get out-
of-time grace notes leading into rhythmic phrases of varying 
lengths. Lots-o-fun.
