Thanks Alastair for your quick answer and for the example,

I guess I didn´t explain well. I think what I am looking for is different.
When I start the DAW I get in QC an increasing count with the measures
numbers (1, 2 , 3, 4, 5, 6, 7, 8, etc...).

So, if I create, for example, a math expression "a > 3" when I get 4 and
the Math expression object is conected to the "enable" circle conector the
circle patch is enabled. That works great.

But I can not imagine how to create an Math expression for send 0 or
disable the circle object when the counter reaches, for example, 8 in the
count?

Sorry if I am not beeing very descriptive.
