When running Frank's exmaple pd patch (and all the others I've tried) under JACK, using the Planet CCRMA version of pd I get lots of IO Errors reported by pd, even though there doesnt seem to be any dropouts, the cpu load is low and jack doesnt report any xruns. Is there a .pdrc file or something where I can set the block size to make it match jacks? Or is there something else wrong? Cheers, Steve
