[PD] getting a messsage at end of [phasor~]

[Marko Timlin]

Hi,
[phasor~] ramps continuosly from 0 to 1. 
I would like to get a [0< message each time [phasor~] reaches its end, thus each time [phasor~] reaches 1.
Seems easy but I got somehow stuck.
Would be very easy if I would have to deal only with ordinary numbers, but in this case I have an audio signal...
Any ideas?

Any help would be highly appreciated.

Marko
