Figure 37 - Map remote control triggers for loading and
unloading a map.
“follow2” would have a single layer made-up of a region covering the whole stage,
with the 30 fixtures set to be followspots and tracker 2 selected. In the “Map
Control” dialog box you could set a “Map load trigger” when DMX channel 512
has a dimmer value between 0 and 127 and a “Map unload trigger” when DMX
channel 512 has a dimmer value between 128 and 255.
When in real-time mode, the MLD software would load and unload the maps when the
console sends the right values through the defined DMX channels. So the MLD is
completely controlled remotely and it appears as one more fixture or device to the
main control console.
IMPORTANT NOTE: Sometimes two or more maps may have certain
“incompatibilities” with each other. The example above for instance, has two maps that
assign the same 30 fixtures to become followspots for two different trackers. If you
load both maps in the real-time mode only the second map will be operative, as the
system follows a “latest takes precedence” DMX priority. Ensure that incompatible
maps are not loaded simultaneously by choosing appropriate map control values that
unload one map before or at the same time than loading the other map. For more
information on real time DMX priorities please refer to the DMX priorities section in
the next chapter.
Side note: You may want to choose to load and unload all your maps using different dimmer
values or ranges in the same DMX channel, or, as in the example above, set different DMX
channels for each map. Some users prefer to use a DMX channel per performer and load and
unload all of his or her maps using dimmer values in that channel. It’s your choice!
