How do I prevent a counter object from looping?
I'm using a counter object to help monitor input from a USB device.
When the device sends a signal to inc/decrement the values I want them
to go up/down and counter does this brilliantly. What I can't get
counter to do is STOP once it reaches an upper or lower limit.
I'm sending a 0 or 1 to the second inlet of counter to regulate
direction when values are within a range and that works perfectly to
set UP or DOWN for the counter. However, when I get to a max or min
value and try to *advance further* in that direction the counter loops
back to the opposite extreme and continues counting from there.
What I want is to have counter respond so that once a min or max has
been met it *will not advance* in that direction any more and only be
able to go in the opposite direction. I imagine that this is a common
need but haven't been able to find any patches that use the technique.
Please write if you have any suggestions. Thank you!

There are outlets on the counter to tell you when min/max values are
reached. Use them to turn off a gate at the counter's left inlet.

just use the 2nd and third outlets to stop the input in some way

Sending a 2 to the second inlet gives the "up & down" direction, so
that it starts moving in the other direction when it reaches the min
or max.

Something like this?:

Will sending an "updown" message to the counter do what you need?

...or just set the counters direction argument to 2.

Chris -- THANK YOU!!! That is doing exactly what I need. I was trying
to use a switch that would trip once a threshold was reached, but the
gates with > and < is much more elegant.
Thanks to others as well. As Don says, "It takes all of us."

You're welcome.
The downside with using the carry and underflow outlets as a couple people suggested is that it's really hard to get your patch in a good state. Counter's carry and underflow outlets are sort of stupid.

if i need a one-time counter from 0 to 17 i
usually use something like [substitute 17 0]
where the "0" turns the metro off and resets
the counter.
