Pure Data externals to work with OSC by mrpeach. udpsend, udpreceive, tcpsend and tcpreceive are byte-oriented externals similar to and based on netsend and netreceive. Start the slackbuild with ALL=YES to build all the objects. In that case, you have more externals, not specific to Open Sound Control. After installation go to Pure Data > Media > Preferences > Path > New and select /usr/lib(64)/pd/extra/mrpeach Or start Pure Data like this: pd -path /usr/lib(64)/pd/extra/mrpeach This requires pd (vanilla) and jack-audio-connection-kit.
