I know from my 1394 work that these things have to be created correctly, but I do not know how to do it. Do you know of any documentation on the right way to get this created? I admit I have not searched the Jack archives yet. What value does this provide, by the way? Jack seemed to be working just fine for me up to now. Thanks, Mark
