QLC+ uses OSC over UDP with auto-assigned ports derived from universe numbers

Fact L2First instrument I · VJing, projection mapping, LED/DMX & videoJ · Audio-visual integration & sync

Open Sound Control (OSC) in QLC+ assigns input ports at 7700 + (universe − 1) and output ports at 9000 + (universe − 1). OSC paths follow /QLC+universe-1/dmx/channel-1. All values use float type. A note for TouchOSC users: the X and Y axes are swapped in QLC+, requiring the Tilt/Vertical auto-detect button to be clicked first. QLC+ includes a pre-configured input profile for TouchOSC Mix16 layout.

Examples

Universe 4: input port 7703, output port 9003. DMX channel 12 path: /3/dmx/11. A tablet running TouchOSC sends fader values to port 7700 and receives feedback at port 9000.

Assessment

QLC+ Universe 4 uses OSC. What are the default input and output port numbers? Write the OSC path for DMX channel 12 on that universe.

“By default the OSC plugin will listen on ports starting from 7700, plus the QLC+ universe minus one. The output, instead, will use ports starting from 9000, plus the QLC+ universe minus one.”
