@whale-av Thanks David. in the mean time i figured some solution my self by using |delay| fed into |float}...|delay| is receiving bang from the key-strokes... will try your solution as well though.

thanks once again...

HI,
being quite new with PD, i am doing and art project where i'm implementing PD as a frequency oscillator. it's an interactive installation where (simply put) participants change the frequency of the sine-wave by pressing keys (N for down and M for up).
What i want to do is that, when there is no one interacting with the piece for, let's say, 2 minutes, frequencies start to change randomly.
I have everything sorted out except one thing and that is how to tell spigot (or should i use something else) to put it self in closed state when there is interaction (someone pressing keys) , and to open again after there is no interaction for a certain period of time.

I'm on mac PD vanilla 0.49-1)

thanks ivan
