Again a ledmapper tip:
In the section where you can make the custom layout for the led fixtures it would be very practical to have the possebility to add "dummy" channels. So you can make a more exended fixture profile.
Most lowres led fixtures have a exended mode in with they run in full rgb mode including a dimmer, strobe and multiple effect channels. In my shows i use a dmx merger to drive the lowres led fixtures from the ledmapper AND patch them on the desk for the most basis "flash options" I would love to be able to make a fixture profile in with i can define one master dimmer on my led fixtures and thus on my video output on the lowres led as they are generaly very very bright.
Hope you like the idear!
