I'm working on a project at the moment using a camera to sense the movement within a certain range -using jit.dx.grab and also cv.jit.perimeter- in order to trigger an audio file on a grove~ pacth when people stand inside the sensing area, and stop the audio file when people leave the sensing area.

When I connect the cv.jit.perimeter data output (number box) to the inputs of a STARTLOOP and STOP buttons in the groove# patch, the data from the perimeter is sent continuously, making the buttons flash constantly.

I've been reading that in order to fix this "signal overflow" -or whatever it is called-, I should use seeplim and/or metro objects.

Any hint or suggestion on how to tackle this problem would be appreciated.

Look at [change] which will bloack repeated values from being sent and stop all your unwanted triggers. That should do the trick.

Thanks Luke, I'll have a look straight away!

Hi Luke, I'm quite new using Max. I made a patch using [change] object but still can't make it work. The audio file plays well, but I can't make it stop yet.

Would you please give me an idea how to fix this?

Have a look at this patch and go through each of the object helpfiles if you don't immediately see what each step is doing. Hopefully it will help you on the way.

sorry for the delay in replaying. Your patch worked really well. That was what I was looking for. I just changed a few things but it works very well.
