Lightning DmxControl is a simple dmxcontroller for Mac OSX with 24 channels and 12 presets. It can output DMX through an Enttec Open DMX USB or Enttec DMX USB PRO Interface. Further, it is remotely controllable by any Midi Controller.
You can create presets by rightclicking a preset fader and choose 'Create Preset from Channels' from the context menu.
You can also use a MIDI Remote to control the faders. To do so, rightclick a fader and choose 'Midi Learn' from the contextmenu. Move a fader on the Midi Remote and it will be coupled.
