report prefered audio device is missing

    May 16 2012 | 10:17 pm
    Hello, I've made a preference file for my patch, with a few parameters, all bounded to pattr object. They are all recalled when the patch is opened by automaticily reading a pattrstorage file. with an adstatut-driver linked to a menu (wich is bounded to a pattr object) I can recall my prefered audio-device. I wonder how I could tell Max to detect if the device stored in the pattr object is missing and report it to the user. same question with a Midi device. any help would be much appreciated. thank you
