Hello, I need to find a way to communicate via OSC with a non-session-manager client (non-mixer) by using a fixed port number. I'm developing a "midi proxy" based on mididings, which allows me to use a Novation Launch Control XL as a controller for various midi devices. Now, I wanted to use it with non-mixer, and since mididings supports osc this is ok. Its interface is pretty basic, there's only a SendOSC function which accepts the destination address, the osc path and optional arguments. My program creates a configuration file with mapping for every physical controller, each of them has a different patch assigned; once the program is loaded in "live" mode it creates a mididing configuration on the fly and runs it. When using non-mixer in standalone mode I can set a fixed port and I'm able to send messages without any problem, since the controllers have their SendOSC command with the "hardcoded" port number. The problem comes when using non-mixer within a non-session, because obviously I cannot manually set the port number for clients. I really tried and looked around for solution on how to communicate with the non-mixer through nsm, but with no luck. I even tried using the /nsm/server/broadcast using the format sf "Non-Mixer.nKWUR/strip/Pianoteq/Gain/Mute" 1.0. The only way I can access the non-mixer is through its randomly created port, which I can find in the log when adding non-midi-mapper to the session. But this is not practical, first of all because I'd have to change the port number in the configuration file every time non-mixer is started, and also because I'd need to add non-midi-mapper and sniff its log. In case you were wandering, I cannot use the midi mapper with mididings, because I need to control other parameters which are not available to it (plugin values). I could try to create an OSC "router", using a fixed receiving port (but I don't know how to find the client port, a part from looking in the nsm log), but I don't like this solution. Am I missing something? Does anybody here have any idea? Thank you in advance, Maurizio
