    Apr 24 2013 | 10:09 pm
    when I active audio with rewire setting, audio launch and some seconds before stop.
    In max window I have this message : ad_rewire: error starting audio. is REWIRE mixer running?
    I used max6 and cubase4 on OSX 10.7.4
    with max5 rewire run good.
    If anyone have an idea how repeat this ???
