Hi! I'm trying to interface Pure Data with jack.osc, but I think I'm missing something :-) At the moment I can connect Pure Data to jack.osc and I've successfully registered the PD client to jack.osc server. I've also successfully executed the "/connect" and "/locate" messages, but I'm having troubles understanding the "/receive" and "/receive_at". The man page (http://rd.slavepianos.org/?t=rju&m=jack-osc.text) says that I must specify a "category" that is a: "bit mask that indicates what categories of notification packets are requested." I've tried in many ways, but it seems that I'm not be able to create the correct OSC message.
