Hi Luca,<br>I asked something similar before, and Frank Barknecht remember me that in Pd,&nbsp; the results of any computation are considered to last 0 ms in logical time, in fact it will take some real time to find it, so in case of real-time applications, it's my understood that normally, if an incoming signal arrives in the middle of a computation, it will be ignored. The other option is to develop something with threads for reading your incoming signals, but then you have to pay special attention to the synchronization of them.&nbsp; In my case it seemed to be a good trade-off to assume my incoming signals one at a time, and spaced in time long enough for my object to finish the calculation, instead of doing the whole thing with threads. <br>I hope this helps, if you find a workaround, please let me know...<br><br><BR><BR>Julian Villegas<br><br>University of Aizu<br>Synthetic Worlds Laboratory<br>Aizu - Wakamatsu Fukushima<br>Japan 965 - 8580<br><br>Me pregunto de un
