Hi,
I almost feel ashamed to look for solutions on the forum here. The issue is apparently simple, I want to make a countdown timer with minutes and seconds, at 00 00 the timer stops. What happens is, if I update my minute counter at 00 the [f] that stores the minute value changes one second 'too soon' , the sequence of remaining time goes

01:02
01:01
00:00
00:59 ...

If I change the same [f] at 59 seconds all goes well - however the timer stops one second too late, at -1 second and displays 59. I've been playing around with this for some time, but my thinking goes in circles.
I attach both counters, one that changes at 00 and the other which changes at 59. They're in the same patch.

maybe something like this.......

Thanks - that was a way to do it I would never think of!

I finally opted to use spigot - once the minute counter reaches 0 spigot opens and then the 'end' is detected not by the minute counter but by the second counter. The idea is of course to generate a soundscape while the clock is running. Now I can even fade out over the last ten seconds...

Thanks again for your time for this issue of little interest. I attach the final version with a nicer look - just for the fun of it.

oh, i like trying to figure out solutions for problems people post here, it helps getting a better work flow with pd and i learn much through it. so, and by the way, i found it interesting!
thanks for the patch .... btw: didn't you use [wrap] for a special reason?

I don't understand yet how to use [wrap] - I thought I would use [max] or [min] when I saw your patch but finally I already had my way to push a zero into the minute counter at stop when it would display '-1' - and the new routine to read from the seconds counter actually made it obsolete.
I will study [wrap] tonight, I will
