As a last example of the possible light control configurations, here is a set-up similar to
the standard one (Figure 12) except that there is also a MIDI link between the MLD and
the console. With this link the MLD may trigger cues in the console and thus control
lights that are not directly connected to it. Also, the console may load and unload MLD
maps using MIDI. This set-up is convenient when all DMX channels are being used for
lighting control. Usually MIDI is not used for lighting control very much, although the
possibility is there. Please note that for this set-up you will need a Roland MPU-401
card to be installed on the MLD PC (this card is quite inexpensive) and your console
will need to have MIDI in and/or out.
Please refer to Appendix D which has a list of all the lights presently supported by the
MLD at this time.
Once your lights have been securely fixed in their final positions, your DMX chain has
been set up, and the fixtures have all been addressed and powered-up, you are ready to
define and calibrate all your lights.
