Hi,<br><br>I'm new to Pd, and I'm trying to write an external and thanks to johannes' HOWTO, the process hasn't been so painful. However, I haven't found how to solve this problem (I tried to look the source code of the pipe object that does something alike, but I couldn't understand... maybe too tired right now):<br>I receive for one inlet a list and perform some computation with the data until a new message (or a bang to the leftmost inlet) arrives or the execution reach a time limit defined by the user as a parameter of the object. The method that do the computation should put whatever value it got to one outlet, and start doing again the computation with the new data. I don't know how to interrupt it whenever it's required. I tried to put the computation inside a loop that checks the value of a member variable, but it never did it and I finished rebooting the machine.<br>In java I could put a listener, but in c I just don't have any clue how to do it and any light will
 be very appreciated.<br><br>Thanks in advance.<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 modo pensativo<br>Que significa ser colombiano?<br>No se le respondi.
