OSC and DMXControl

OSC – O pen S ound C ontrol Protocol A candidate for lighting applications? Frank Burghardt, Markus Minini 2010-Jan-23 www.DMXControl.org

The OSC story – some examples (sound applications) www.DMXControl.de 2010 If you want the ultimate in external control of Resolume, the Open Sound Control (OSC) protocol is the answer. OSC is becoming increasingly popular and is used by programs like MAX/MSP, VVVV and Reaktor (Native Instruments) OSC can be seen as a successor of MIDI and offers a much higher accuracy and is more flexible because it can be sent over a network including wifi. (Resolume Manual) Well, my wish has been granted, the latest AlgoScore supports OSC, and I'm a happy guy . … most controllers have to overcome a technical legacy , namely MIDI. Because many controllers can be connected via USB, it is possible to use protocols with higher resolution, of course in particular OSC. OSC opens a new era in the field of real-time control and human-machine interfaces (Lumor Manual)
