We have discussed in recent posts the possibilities of WORK LM5 device, and the first conclusion we made is that it actually depends on your creativity. Nevertheless, the most interesting way to use it is probably to control a RGB system with an iOS device.
Immagine a RGB system for the photo above. Several RGB LED bars were used to wash the wall. The same installation can be done in any small bar/lounge, to easily change lighting color of the different areas (bar, outside garden terrace, etc).
Let?s see how to install it and how to customize it.
We need the following material:one LM 5 connected to an Ethernet networkan iOS device (iPhone/iPad) connected to the same Ethernet network vía Wifi (our advice is to protect it using WEP/WPA or MAC filter).a DMX cable to connect LM 5 to the DMX installationthe units of the RGB lighting system (e.g. RGB bars, spots, LED strips, etc.)

3. RGB lighting system control
The material is now installed, so what you need is a layout to control LM 5. You can download one of the available layouts in the LM 5 microsite or create your own layout. If you decide to make your own, use one of the layouts of the microsite as a base for your new layout design, it will be easier.
I should like to open a short parenthesis to clearly understand how does LM 5 work and what are the layouts for.
LM 5 interprets OSC orders, a common protocol mostly used in the music field and more and more in softwares like VJ/media servers. It is very easy to use and fast. OSC is almost like MIDI but for Ethernet and faster (more information in www.opensoundcontrol.org).
There are many applications for iOS mobile devices and for Android (even if there are many things to improve). The most famous for iOS are TouchOSC (www.hexler.net) and Lemur (www.liine.net). We have decided to use TouchOSC for the example because it is much more simple (we will prepare soon a new tutorial using the powerful Lemur application).
Now let?s explain what is a layout for. Lemur and TouchOSC both make possible to design screen in which users ?draw? interfaces like faders, buttons, LEDs, encoders, etc. Users easily associate them to an OSC command to execute it. For example, if you want to change DMX value (by moving a fader) for channel one between 0 and 255, you should do this:
In this example we have associated the order /dmx/set/ch/1 to a fader, so it is possible to get any value from 0 to 255 by moving this fader. That?s easy, isn?t it? You can do the same thing with any parameters and, with a little patience and creativity, get something like this:
*All commands supported by LM 5 are available in the user manual.
We have already published many layouts and they can be downloaded in the LM 5 microsite. You can use them without changing anything or, if you prefer, design your own layouts using them as a base.
In this case we have programmed two RGB zones with the following configuration:ZoneDMX red channelDMX green channelDMX blue channel11232456
We have a Master fader (controlled with the channel ?-1? ) and a blackout (blackout command). The layout can be fully customized to get screens like the one before, it is all about imagination.
It is very interesting to edit/design simple layouts for users who do not have any knowledges and who do not have to program anything (like the bartender of the installation). The idea is to provide them an intuitive interface to launch scenes and control colour/dimmer, whereas we will use more elaborate layouts to program scenes.
If you want more information about how to design your own layouts, take a look at the tutorials of TouchOSC and Lemur.
