Colour picking in Jitter

Hi all,

I'm doing a project for uni and trying to get max to trigger samples using the jitter functions.
Using jit.pwindow and jit.scissors I intend to use 3 LED's to trigger different samples in each separate panel that is cut up by the jit.scissors object. Ive managed to get the colour to trigger the sample but it continuously sends bangs so the sample is constantly being re-triggered.
Is there anyway I can get around this?
I also only want it to notice the colour once, and then disregard that information until it appears again.
Is this possible?
I've tried using jit.3m, then using the / object and round object to make it trigger less often, but the functionality isn't great.

Many Thanks,

Roy
