thanks MJ and Fokko, I try to summarize my now extended (but most likely not 100% correct) knowledge about data transfer to a Lanbox with UDP: INSIDE THE LANBOX: in the "global settings..." UDP tab: - "from sender": anyone:4777 there's no need to change this setting. - "copy light channels" and "to light channels" are quite self explaining. But still one QUESTION: What happens if I don't enter anything into this fields and transmit UDP to the box? Nothing, I guess. - "of mixer": the UDP-in will control the channels in the mixer, which is located below all layers. So I have to delete all layers or turn off the desired channels in all layers for actually made UDP change the desired DMX channel. - "of layer": if this is selected, the UDP-in is routed to the specified layer. You need to turn on those channels in that layer for enabling the control via UDP. INSIDE MAX (OS X): about the "lcudp-pack" object: - input 1: it likes bangs, ints and lists. a list can look like "0 0 0 255" for setting the first three DMX channels to 0 and channel 4 to 255. such a list can contain as many entries as the box is able to handle. - input 2: here you define an offset for the first channel. "255" to input 1 and an offset of "10" would set channel 10 to 255. - input 3: set it to 1-63 if you wanna write to a corresponding layer (1=A,2=B,...). set it to 254, if you wanna write direct to the lanbox mixer, which has lower priority than the layers. - input 4: here you can define the message type as described in the Lanbox Reference manual on page 83. "1" results in a buffer write. "2" will result in a buffer broadcast. - output: obviously this needs to be connected to an otudp input. So I guess if I send a buffer broadcast out of MAX, the Lanbox will receive it and will pass it to a layer or the mixer as specified in the global settings UDP tab. In this configuration input 3 of the MAX object lcudp-pack will be ignored. Second possibility: I send the UDP packet as buffer write (feed a 1 into input 4 of lcudp-pack). in this case input 3 won't be ignored. but I guess the UDP settings in the Lanbox. Right? Wrong? Yes Fokko, you told me that it's not possible to write to a layer, but why is this input 3 there? Please correct any of the mentioned things if it's obviously wrong to you. Thanks in advance. Sorry, wasn't able to reach demo.lanbox.com today and the next time I go to the club where my lanbox is installed is tomorrow, so couldn't try it yet by myself. btw: I wanna use a MIDI-Faderbox connected to a Notebook, where a MAX patch and LCedit+ are running. The MIDI-Faderbox will transmit it's control changes to MAX where they will be converted to UDP and sent to the lanbox to take over control of a specified layer with some active channels. That would be a great wireless control unit, that can be placed everywhere in the venue (you can even walk around with that), most likely next to the audio-FoH place. btw. my light desing is heavily based on layers, that's why I wanna have "UDP to layer". Hope this is possible somehow. I don't wanna control everything from MAX without using most of the lanbox features (layers and cues). Especially when the computer fails on a live show... kind regards, sam
