Looking for a ugen: Trigger on value change?

[bitbutter]

I think i might be overlooking something, but so far I've not been able to find a ugen that can be asked to monitor a signal, and generate a trigger any time that signal's value changes (In my case the signal will have integer values from 0 to 7). Is there a Ugen, or combination of ugens, that i can use to achieve this?

Something like:

Code:

{Trig1.kr(HPZ1.kr(MouseX.kr(0, 1)).abs).poll}.play(s)

Hope that helps!
