Opening Max 5 Collective in Max 6 - No Audio

    Jan 18 2012 | 12:39 am
    I have a number of mxf collectives created in Max 5. If I open them in Max6 or Max Runtime 6, I get no audio output through the dac. I can see that signal processing is occurring, but no actual sound comes out. If I open the original maxpat file in Max 6 and rebuild it as a collective--without changing anything--it works just fine. Do I really need to rebuild all these objects to make them compatible with version 6?
